The holy month of Ramadan
Common amaal for Laylat-ul-Qadr
Eve of Destiny, 19th,21st,23rd
Eve of Destiny (Laylatul Qadr) is the night, which is the most blessed and excellent of all nights. A prayer during this night is superior to the prayer of a thousand months. The destiny for the year is decided on this night. The Angels and Roohul Ameen (a highly dignified Angel) descend on this earth, with the permission of Allah (swt) & call on the Imam of the time, and what is ordained (by Allah) for everybody is presented before the Imam. Our destiny to large extent can be changed in this very night and much depends on us, how we decide to utilize each single moment of this blessed month of Ramadhan.

as well as all the believing men and women;

مِنَ ٱلْمَغْفِرَةِ فِي هٰذِهِ ٱللَّيْلَةِ
min almaghfirati fi hadhihi allaylati
that is Your forgiveness at this night,

وَاتْمِمْ عَلَيَّ مَا آتَيْتَنِي

Alaahumma inni asaloka be kitaabekal munzale Wa maa feeh,
O Allah I beseech Thee in the name of Thy revealed Book and that which is in it,

وَ فِيهِ اسْمُكَ الْأَكْبَرُ وَ أَسْمَاؤُكَ الْحُسْنَى وَ مَا يُخَافُ وَ يُرْجَى أَنْ تَجْعَلَنِي مِنْ عُتَقَائِكَ مِنَ النَّارِ
wa feehismokal akbaro wa asmaakal husnaa, wa maa yokhaafo Wa yurjaa an taj-alani min otaqaaeka minan-Naar
and Thy Great Name and Thy (Other) beautiful names are in it, and in it there is that which warns and gives hope to include me among those who have been set free from the Hellfire.

After that one should pray to God for any needs of his.

and for the sake of those believers who have been praised therein,

وَبِحَقّكَ عَلَيْهِمْ
we be haqqeka alaihim
and in the name of Your obligation to them,

فَال أَحَدَ أَعْرَفُ بِحَقّكَ مِنْكَ.

Ziyarat of Imam Hussain (as) (on Laylatul Qadr)
Recite the Ziarat of Imam Hussain (A.S.)
According to Hadith, during Lailat-e-Qadr an angel proclaims from the Arsh (throne) on the Seventh sky that Allah has forgiven who have visited the grave of Imam Hussain (as). While performing Ziyarah of Imam Hussain (as), remind yourself that on this night, the souls of 124,000 Prophets (peace be upon them all) visit Imam, who is aware of our inner spiritual reality and is hurt and repulsed by our record of repeated evil deeds, indifference to God’s commandments; thus, we should avoid disgracing ourselves in that great audience of Imam. Also, associate the themes in the ZIYARAH of: - Firm bond of love and obedience of God (SALAT). -Economic betterment of community (ZAKAT). -Overall mobilization of forces towards virtue (AMR BIL MA`RUF).  -Overall cleansing of evil from society. -All-out war in all spheres of life to promote truth (JIHAD). -Tremendous endurance of all ensuing difficulties (SABR). -Complete distancing (LA`NAH) from all forms of injustice (DHULM) with destiny- shaping opportunity of this night and resolve to become on active player in improving the future in preparation for the REAPPEARANCE OF AL-MAHDI..
