Dua'a for Memory and Speech
If one fails to remember an event or written text or spoken words, according to Imam Jafar bin Muhammad al Sadiq one should put the right hand on the forehad and recite:
INNEE AS-ALUKA YAA MUD'AKKIRAL KHAYRI WA FAA-ILAHOO WAL AAMIRA BIHEE AN TUS'ALLIYA A'LAA MUH'AMMADIN WA AALI MUH'AMMADIN WA TUD'AKKIRANEE MAA ANSAANEEHISH SHAYT'AAN
I beseech You, O He who reminds about doing good, does good and commands to do good. Send blessings on Muhammed and the family of Muhammed and let me remember what shaytan makes me forget.
According to Imam Ali ibn abi Talib to retain in memory whatever one listens or reads, recite the following dua'a after every obligatory salat.
In the name of Allah the most kind the most merciful.
Glory be to Him who does not treat the citizens of His kingdom unjustly.
Glory be to Him who does not let the torment and pain come suddenly upon mankind.
Glory be to the compassionate the merciful.
O Allah, fill my heart with true enlightenment, wisdom, understanding and knowledge.
Surely you are able to do all things.

DUA'A 14 Whoever writes surah Bani Israil with saffron, washes it with pure water and drinks it will grow in wisdom and have fluent speech.
DUA'A 15 To speak clearly and fluently recite surah al Jumu-ah a great deal, and to have a photographic memory learn surah al A-laa by heart.
Memory and Retention Ayatullah ‘Ali Qadhi al-Tabataba’i would advise one to recite Ayat al-Kursi [2:255-257] and Ma’udhatayn (Surat al-Falaq and Surat al-Nas) for strengthening one’s memory
Reciting regularly Salwaat on the holy prophet & his household is also a method to improve ones memory
Take 4 or 7 almonds and pray salwat then pray "Ya Zul Jallale wal Ikraam" 11times, again salwat then and blow ( breathe on the almonds with the breath of the Zikr as you recite it ) on the almonds and eat them first thing every morning, Inshallah it will help your memory
From Baqiyatus slaehat ( margins of Mafatih ) :-
It is reported in 'Makaarimul Akhlaq' from Imam Muhammad Baqir (a.s.) and Imam Sadiq (a.s.) that one should write on a clean vessel with safron the Chapter of Al-Hamd, Ayatul Kursi, the Chapters of Qadr, Yasin, Waqiah, Hashr, Mulk, Ikhlas, Falaq and Nas and should then wash them with Zamzam water, rain water or clean water and add in the water about two grams of 'kandaroo', fifty grams of sugar and fifty grams of honey. At night it should be kept under open sky on iron.
At the end of the night one should recite two rakaats in each of which after the recitation of the Chapter of Al-Hamd, the chapter of Ikhlas be recited fifty times.
On completion of the salaat, one should drink the water which is good and tested
The following dua’a was taught by the Holy Prophet (S.A.) to Imam Ali (A.S.), to be recited after every obligatory Salaat, for developing a flawless memory:
Glory be to Him who does not treat the citizens of His Kingdom unjustly and harshly, Glory be to Him who does not let torment and pain come suddenly upon mankind, Glory be to the Compassionate, the Merciful. O Allah fill my heart and mind with true enlightenment, discerning intelligence, quick understanding and knowledge, Verily Thou art able to do all things.
سُبْحانَ مَنْ لا يَعْتَدي عَلى أهْلِ مَمْلَكَتِهِ سُبْحانَ مَنْ لا يَأخُذُ اَهْلَ الاَْرْضِ بأَلْوانِ الْعَذابِ سُبْحانَ الرَّؤوُفِ الرَّحيمِ اَللّـهُمَّ اْجَعلْ لي في قَلْبى نُوراً وَبَصَراً وَفَهْماً وَعِلْماً اِنَّكَ عَلى كُلِّ شَي قَديرٌ .
Proven Supplication for increasing memory ( Tohfatul Hashmiya)
Write on seven pieces of sugar and eat a piece everyday. Write on the first one:
فَتَعٰلَی اللهُ الْمَلِكُ الْحَقُّ.
Fataa’a’lallaahul malikul haqq
Supremely exalted is therefore Allah, the King, the Truth,
and eat it on Saturday, and on the second write:
وَ قُلْ رَّبِّ زِدْنِيْ عِلْمًا.
Wa qur rabbi zidnee i’lmaa.
And say: O my Lord! Increase me in knowledge.
and eat it on Sunday, and on the third write:
لاَ تُحَرِّكْ بِهِ، لِسَانَكَ.
Laa tuh’arrik-bihi lisaanak.
Do not move your tongue with it
and eat it on Monday, and on the fourth piece write
إِنَّ عَلَيْنَا جَمْعَهُ وَ قُرْأَنَهُ.
Inna a’lainaa jam-a’hu wa qur-aanah.
Surely on Us (devolves) the collecting of it and the reciting of it.
and eat it on Tuesday, and on the fifth piece write:
فَإِذَا قَرَأَنَهُ فَاتَّبِعْ قُرْأَنَهُ.
Fa-idhaa qaraa-nahu fattabi’ qur-aanah.
Therefore when We have recited it, follow its recitation.
and eat it on Wednesday, and on the sixth piece write:
سَنُقْرِئُكَ فَلاَ تَنْسٰى.
Sanuqri-uka falaa tansaa.
We will make you recite so you shall not forget,
and eat it on Thursday, and on the seventh piece write:
إنَّهُ يَعْلَمُ الْجَهْرَ وَ مَا يَخْفٰی.
Innahu ya’lamul jahra wa maa yakhfaa.
Surely He knows the manifest, and what is hidden.
and eat it on Friday.
Memorization would became easy for one who does this for seven days, and his tongue would become eloquent and his memory will increase.
Another Supplication for Memory
The Prophet (s.a.w.s.) said to Ali (a.s.): If you intend that you retain all that you hear, then recite the following after every ritual prayer:
سُبْحَانَ مَنْ لاَ يَعْتَدِىْ عَلٰی اَهْلِ مَمْلَكَتِهِ، سُبْحَانَ مَنْ لاَّ يَاْخُذُ أَهْلَ اْلاَرْضِ بِأَلْوَانِ الْعَذَابِ، سُبْحَانَ الرَّؤُفُ الرَّحِيْمُ، اَللَّهُمَّ اجْعَلْ فِیْ قَلْبِیْ نُوْرًا وَ بَصَرًا وَ فَهْمًا وَ عِلْمًا، إِنَّكَ عَلٰی كُلِّ شَیْءٍ قَدِيْرٌ.
Sub-h’aana mallaa ya’tadee a’laa ahli mamlikatih. Sub-h’aana mallaa yaa-khudhu ahlal arz”i bi-alwaanil adhaab. Sub-h’aanar ra-oofur rah’eem. Allaahummaj-a’l fee qalbee nooranw wa bas’araa. Wa fahimanw wa i’lmaa. Innaka a’laa kulli shai-in qadeer.
Glory be to the One who does not oppress His subjects, Glory be to the One Who does not subject the people of the earth to various punishments, Glory be to the forgiving and the Merciful, O Allah, put in my heart a light and perception and understanding. Indeed You are powerful over all things.

I Have Been Sent As A Teacher –Prophet (saww)
Aids to Memory: Listing
Prophet Muhammad (saww) used several techniques and methods to teach Islamic rules to his people. One of the techniques he used was ‘Aids to Memory’ The Prophet was adept at using to memory, so as to make things clear.
One device was to structure the material in a few numbered points; either three or five are common. For instance: ‘Islam was built on five (pillars) …..
‘Three things will make a man a through hypocrite: when he speaks he lies, when he promises, he breaks his promises, and when he is trusted, he breaks his trust’.
Frequently, we find a grand total is given for emphasis. Forcing the material into specific numbers in such a way makes the listener eager to get the right number. Thus you may sometimes find a companion reporting: ‘… and I have forgotten the third.’ By comparing his version to those of others, a full list can be obtained.
Sometimes, before listing the item, the Prophet would pause, to arouse curiosity: There are three persons God will not speak to on the day of Judgement: (and he repeated this statement three times and paused). Abu Dhar asked: ‘They are lost and ruined indeed! Who are they, O Prophet of God?’
Aids to Memory: Illustrations
A similar logical structuring of material is found in general statements followed by illustrations, such as: ‘Each of you is a shepherd, and will be responsible for his charges: the man is a Shepard in his house,’ he then continues with ‘the woman, the child, the servant…’ He then repeats the general statement at the end.
Aids to Memory: Questions
It should also be noted that the question and answer technique, and the suspense it involves, was an aid to memory: ‘What day is this?’ he asked. ‘Friday,’ they answered. ‘What month is this?’ Dhul Hijjah.’ ‘What place is this?’ The sanctuary’.
‘Then you should know that your blood, your money, your honour, is as inviolable to you as they are in this day, this month and this place.’ Here he used the technique even in a sermon.
Aids to Memory: Brevity
Other devices to aid memory included brevity of statement; formulating material on the same order and pattern as a Quranic verses; rhythmic statements (which is very common); explanation of cause’ and contrast, as in: ‘the upper hand is better than the lower one’ (in giving).
Aids to Memory: Body Language
Body language was also used to give particular emphasis to important points: Reclining, he asked: ‘Shall I tell you of the greatest sins?’ After mentioning the first two he sat up, and said: ‘and indeed: giving false testimony, giving false testimony, giving false testimony.’ And the narrator said: ‘He went on saying this until we began to say: “When will he stop?”
The Prophet saw a crowd of women and children coming back from a wedding celebration. So he stood up to his full height and said: ‘By God! You are amongst the dearest to my heart!’ repeating this three times.
He looked at the full moon and said to his Companions: ‘You will see your actions as clearly as you see this. So if you can some prayer before sunrise or before sunset, don’t miss opportunity.’
Aids to Memory: Incentives
This demonstrates the Prophet’s skill in arousing incentives to learn and do-good deeds, rather than asking for an action to be done.
A man asked: ‘Tell me something which if do it, I will enter Paradise.’ The Prophet told him to worship God alone, do the prayer, and pay the zakah and fast in Ramdhan’. The man said: ‘I swear by God, I will not do any more than that.’ The Prophet commented: ‘If it pleases any of you to look at a man who will be one of the inhabitants of Paradise, he should look at this man.’
Ibn Masud also reported that the Prophet once drew a diagram on the sand to illustrate that man cannot escape death and the many accidents that befall him in his life: that is, if he escapes one he will be caught by another.
Aids to Memory: Simple Language
The Prophet used simple, clear language - he hated obfuscation. One of the highly appreciated qualities of hadith material in Arabic isjawami al-kallim, that is, concise, all embracing statements: A man asked the Prophet: ‘Tell me something about Islam which I can ask of no one but you.’ He answered: ‘Say, “I believe in God”, and thereafter be upright.’
When a man asked him how to perform the rites of ‘Umrah he replied: ‘Do as you do on Hajj.’
Once he said to his companions ‘Leave what makes you doubt for that which does not make you doubt.’
And also it is reported that he said ‘If you feel no shame, then do as you wish.’
Aids to Memory: Paradoxes
In many hadiths the Prophet surprises the listener with the unexpected poses of a paradox. Once he said: ‘The portion given away in charity decreases no money.’
On one occasion they killed a sheep and began to give it away in charity. He asked ‘Aisha, how much is left?’ She said: ‘It has all gone except the shoulder.’ He replied: ‘No, it all remains except the shoulder.’
Once he said: ‘Fasting people will enter Paradise through the gate of Al-Rayyan (the one whose thirst has been quenched).’
Aids to Memory: Images
In the hadith, powerful images are expressive, and impress themselves on the memory: ‘Let no one fall on his wife as a male donkey falls on a she-donkey; send a messenger first.’ They asked what messenger, he said: ‘A kiss.’
He also said: ‘When one of you gives charity - and God only accepts what is good - God receives it in his right hand and rears it as one of you rears his young foal, until it becomes as big as a mountain.’
He said: ‘Two hungry wolves set loose in a flock of sheep would not wreak more havoc than a man’s excessive eagerness to amass wealth and status harms his religious practice.’
Aids to Memory: Balanced and Comprehensive Statements
For example Prophet (s) would say: ‘Relieve the distressed; feed the hungry, visit the sick.’
He also said: ‘The tooth-stick cleans the mouth and pleases the Lord.’
Aids to Memory: Emphasis
Emphasis is also a common feature of hadith language. This is achieved through oaths such as: ‘By Him who holds my soul in His hands ….!’
Intensity is also expressed by using such empathic particle as: inna, add, ladad, alal and halla.
