Imam al-Hasan al-`Askari (peace be upon him) is also reported to have said that whoever offers on Fridays a four unit prayer; reciting in each unit Surah al-Fatihah, Surah al-Mulk, and Surah Fussilat (No. 41), Almighty Allah will allow him Paradise, grant him the right to intercede for his household, and guard him against the grave pressure and the horrors on the Resurrection Day.
When the reporter asked Imam al-`Askari (peace be upon him) about the best time of offering these prayers, the Imam (peace be upon him) answered, “The best time is the period between sunrise and midday.”
wa anta ya mawlaya karimun min awladi alkirami
and you, my master, are generous and the descendant of the generous people,
وَمَاْمُورٌ بِٱلضِّيَافَةِ وَٱلإِجَارَةِ
wa ma'murun bilddiyafati wal-ijarati
and you are commanded to receive your guests and neighbors hospitably;
fa-adifni wa ajirni
so, receive me as your guest and neighbor.
صَلَوَاتُ ٱللَّهِ عَلَيْكَ
salawatu allahi `alayka
May Allah’s blessings be upon you
وَعَلىٰ أَهْلِ بَيْتِكَ ٱلطَّاهِرينَ
wa `ala ahli baytika alttahirina
and upon your Household, the immaculate.
Shaykh al-Tusi, in Misbah al-Mutahajjid, and Sayyid Ibn Tawus, in Jamal al-Usbu`, have mentioned within the recommended acts on Fridays that it is recommended to visit the Holy Prophet (s) and the Holy Imams (peace be upon him) on Fridays. Imam Ja`far al-Sadiq (‘a) is reported to have said that one who intends to visit the tombs of the Holy Prophet, Imam Ali Amir al-Mu'minin, Lady Fatimah al-Zahra', Imam al-Hasan, Imam al-Husayn, and the Holy Imams (as) while he is in a remote place may bathe himself on Friday, put on two clean garbs, go to a desert, -or go up to a housetop, according to another narration- and then offer a four unit prayer reciting any Surah he can recite. When he finishes the prayer, he may stand up, face the kiblah direction, and say the following:
اَلسَّلاَمُ عَلَيْكَ ايُّهَا ٱلنَّبِيُّ
alssalamu `alayka ayyuha alnnabiyyu
Peace be upon you, O Prophet
وَرَحْمَةُ ٱللَّهِ وَبَرَكَاتُهُ
wa rahmatu allahi wa barakatuhu
and be upon you Allah’s mercy and blessings.
wa alssalamu `alaykum wa rahmatu allahi wa barakatuhu
Peace and Allah’s mercy and blessings be upon you all.
According to numerous narrations, the Holy Prophet (s) is informed about the greeting of those who greet him and the prayers of those who invoke Allah’s blessings upon him wherever they are. In this respect, a Hadith reads that an angel is commissioned to respond to everyone who says,
salla allahu `ala muhammadin wa alihi wa sallama
Allah may send peace and blessings upon Muhammad and his Household,
by saying, “peace be upon you, too.” That angle, then, tells the Holy Prophet (s) that so-and-so has greeted him; therefore, the Holy Prophet (s) says, “May peace be upon him, too.”
According to a narration, the Holy Prophet (saw) has said, “He who visits my tomb after my death will be considered to have immigrated to me in my lifetime. If you cannot visit my tomb, you can send me greetings, for they reach me.”
It is also advisable to repeat the following words that Imam `Ali (as) mentioned in one of his sermons on Friday, as is cited in the book of al-Rawdah min al-Kafi, representing an invocation of Allah’s blessings upon the Holy Prophet (s):
waj a’lho lanaa quwwatan feemaa tohibbo, yaa arhamar raahemeen.
and make it for us strength in what You like, O the most merciful of the merciful ones.
Sayyid Ibn Tawus quoted Imam al-Hasan al-`Askari (peace be upon him) to have said: In the books of my forefathers (peace be upon them), I have read that whoever offers on Saturdays a four unit prayer; reciting in each unit Surah al-Fatihah, Surah al-Tawhid, and yah al-Kursi, Allah the Almighty and All-majestic will grant him the rank of the Prophets, the martyrs, and the righteous people. How excellent the company of these is!
Imam al-Hasan al-`Askari (peace be upon him) is also reported to have said that whoever offers on Sundays a four unit prayer; reciting in each unit Surah al-Fatihah and Surah al-Mulk, will be allowed by Almighty Allah to occupy any place in Paradise he likes.
ana laki musaddiqun sabirun `ala ma ata bihi abuki wa wasiyyuhu salawatu allahi `alayhima
I verify that you were patient about what came upon your father and his his successor peace be upon both of them
وَأَنَا أَسْأَلُكِ إِنْ كُنْتُ صَدَّقْتُكِ
wa ana as'aluki in kuntu saddaqtuki
I now beseech you by my belief in you
إِلاَّ أَلْحَقْتِنِي بِتَصْدِيقِي لَهُمَا
illa alhaqtini bitasdiqi lahuma
to attach & associate me with my belief in both of them
so that I will be delighted.
فَٱشْهَدِي أَنِّي ظَاهِرٌ بِوَلاَيَتِكِ
fash-hadi anni zahirun biwilayatiki
So, testify for me that I am totally loyal to you
وَوَلاَيَةِ آلِ بَيْتِكِ
wa wilayati ali baytiki
and to your Household;
صَلَوَاتُ ٱللَّهِ عَلَيْهِمْ أَجْمَعينَ
salawatu allahi `alayhim ajma`ina
peace of Allah be upon them all.
Imam al-Hasan al-`Askari (peace be upon him) is also reported to have said that whoever offers on Mondays a ten unit prayer; reciting in each unit Surah al-Fatihah once and repeating Surah al-Tawhid ten times, Almighty Allah will grant him on Friday light that shines the place of the Assemblage (on the Resurrection Day) due to which all the creatures of Almighty Allah will wish to have its like on that day.
Imam al-Hasan al-`Askari (peace be upon him) is also reported to have said that whoever offers on Tuesdays a six unit prayer; reciting in each unit Surah al-Fatihah, the last two verses of Surah al-Baqarah (i.e. amana al-rassulu…), and Surah al-Zalzalah, Almighty Allah will forgive all of his sin as if his mother has just given birth to him.
Imam al-Hasan al-`Askari (peace be upon him) is also reported to have said that whoever offers on Wednesdays a four unit prayer; reciting in each unit Surah al-Fatihah, Surah al-Tawhid, and Surah al-Qadr, Almighty Allah will accept his repentance from all sins and will give him in marriage a Paradisiacal woman.
Imam al-Hasan al-`Askari (peace be upon him) is also reported to have said that whoever offers on Thursdays a ten unit prayer; reciting in each unit Surah al-Fatihah once and repeating Surah al-Tawhid ten times, the angels will say to him, ‘Ask, and you will grant it.”
