The A'maal of Shab-e-Qadr are of two kinds. Some are common to all the three nights. Others are for particular nights. The common A'maals are:
1) To take a bath. Allama Majlisi says, "It is better to take a bath befor sunset so that the night prayers may be performed after one's bath."
2) To offer two Rakats Namaz. In every Rakat recite Sura-al-Hamd. (Sura Fateha) and Sura-al-Tauhid (Sura Ikhlas) seven times and after finishing the prayer recite: 70 times
"Astagferullaaha wa atoobo elaihe,"
i.e. "I repent for my sins and seek pardon from God."
3) The Quran should be opened and placed in front. Then one should recite,
"Alaahumma inni asaloka be kitaabekal munzale wa maa feeh, wa feehismokal akbaro wa asmaakal husnaa. wa maa yokhaafo wa Yurjaa an taj-alani min otaqaaeka minan-Naar,"
i.e. "O Allah treat me as one of those who have obtained deliverance from hell. in the name of this holy Book sent by Thee, whatever there be in the Book, including Isme-e-A'azam and Azmaa-e-Husnaa, and the things to be dreaded, the things that may be expected and desired, like blessings of paradise. Do forgive me through the grace of this book."
(After this he may beg from Allah whatever be wants).
4) He should place the Holy Quran on his head and say,
"Allaahumma be haqqe haazal Quran we be haqqe man arsaltahoo beh, wa be haqqe kulle momenin madahtahoo feeh, we be haqqeka alaihim fa-laa ahada a'arafo be haqqeka mink",
i.e., "O Allah! I appeal to Thee in the name of this Quran and the Rooh that was sent along with it, and in the name of the Momin (believer) whose praise is contained in this Book and Thy obligation that is on them. No one else recognises the right and truth more that Thee,"
(After this he should repeat 10 times each):-
Beke ya Allaaho
Be Muhammadin
Be Alliyin
Be Faatema
Bil Hasane
Bil Husaine
Be Ali-ibnil Husain
Be Muhammad ibne Aliyin
Be Ja'far ibne Muhammadin
Be Moosabne Ja'farin
Be Ali-ibne Moosa
Be Muhammad ibne Aliyin
Be Ali-Ibe Muhammadin
Bil Hasan ibne aliyin
Bil Hujjate-il-Qa'eeme
(Then he may beg from Allah whatever he wants).
(5a) To recite the Ziarat of Imam Husain(A.S.), Ziarat-e-Waris. According to Hadis, during Shab-e-Qadr an angel proclaims from the Arsh (Throne) on the Seventh sky, "Allah the benevolent forgives him, whosoever performs the Ziarat of Imam-e-Husain".
(5b) To recite Du'a Jaushan-e-Saghir.
6) One should keep oneself awake throughout these three nights. The vigil during these nights carries great Sawab (heavenly reward).
7) To offer 100 Rakats of Namaz. It has been highly recommended to recite after Sura Fateha (Sura-al-Hamd) 10 times Sura Ikhlas (Qul Howallah).
8) "Astagferullaah Rabbi wa atoobo elaihe" 100 times (i.e., "I repent for my sins and I seek pardon from God who is my Sustainer").
9) "Allaahummal'an qatalatal Ameerul Momeneen" 100 times (i.e., "O Allah! Thy contempt be upon the assassin of Ameerul Mimeneen Ali ibne Abi Talib").
10) To recite the following Suras from the Holy Quran:
ANKABOOT (The Spider) 29th Sura.
ROOM (the Roman Empire) 30th Sura.
DUKHAN (Smoke or Mist) 44th Sura.
11)This du'a may be recited:-
I have passed the evening as a very humble servant of Thee. I have no control over my gains and losses. I cannot remove any evil from myself. I bear testimony against myself. I admit my weakness and inability to manage my affairs. Bestow Thy blessings on Muhammad (S.A.W) and his Aal (A.S.). Whatever Thou hast promised, fulfil. Verily! I am Thy humble, weak and destitute servant. O Allah! let me not forget the blessings that Thou hast bestowed on me and let me not be forgetful of Thy kindness. Do not deny me the acceptance of my prayer, though it may be delayed, whether it pertains to sorrow or happiness, peace and tranquillity or hardship and vicissitudes or to invocation for blessings. Thou hearest and acceptest invocations in every condition.
The Holy Prophet (S.A.W.) when asked what should one beg of Allah during these nights, said: "Ask for your safety (here and in the hereafter)."
O Allah! Whatever is decreed and ordained by Thee during Laila tul Qadr (Night of Power) is final and of wisdom. Whatever changes were effected in the night in previous decrees could not be changed by anybody else. Do let me be one of those whose Haj is acceptable, whose efforts are rewarded, whose sins have been pardoned and whose errors have been forgiven. Add to the span of my life increase my livelihood and fulfil my righteous desires.
O One, who was before everything and then brought everything into existence. Thou wilt remain whilst all else will be destroyed. O the One, sole and solitary exception whom there is none else in the high heavens or low earths or above and below them or in between them who is worth worshipping. Only Thou art the deity and none else deserves to be worshipped. To Thee alone is due the praise which cannot be offered to anyone but Thee. Therefore bestow peace and blessings on Muhammad (S.A.W.) and Aal-e-Muhammad (A.S.) such as nobody else has the power to bestow.
O One who turns day into night and night into day. O One, who brings out the living from the dead and the dead from the living. O one, who gives sustenance to whomsoever and whatsoever He likes. O Allah! O Merciful! O Allah! O Allah! O Allah! The best names are for Thee alone, The best attributes are for Thee. The grandeur and the glory are for Thee. I beg of Thee to bless Muhammad (S.A.W.) and his Aal (A.S.). Write down my name in this night with the fortunate ones. Let my soul be in the company of the martyrs. Let my good acts be reckoned as "lliyeen" (exalted). Let my sins be condoned. Bestow on me that belief by virtue of which Thou may be nearest to my heart, that "Iman" which may remove all doubts from my mind. Let me be satisfied with whatever Thou hast ordained for me. Let me have the virtues of this world and of the hereafter. Save me from the fire of hell.Let me always attend to my duty to praise Thee and to thank Thee, and let me present myself in Thy court. Do bestow the same "taufique" (guidance) to me which Thou hast bestowed upon Muhammad (S.A.W.) and his Aal (A.S.).
O Lord of Lailatul Qadr! (Night of Power). Who has made it better than a thousand months! O the Lord of the day and the night and the mountains and oceans, the Lord of light and darkness! O the Lord of the earth and the skies! O the Creator! O the designer! O the Compassionate! O One who favours! O Allah, who maintains everything! O Allah! O the most benevolent! O Allah! O the creator of new things! O Allah! O Allah! O Allah! The best names are for Thee alone. Thou hast control over all virtues. I ask Thee to send blessings on Muhammed (S.A.W.) and his Aal (A.S.). Write my name, in this night of Qadr, among the names of the fortunate. Let my soul keep the company of the martyrs. Let my good deeds be reckoned with "Illiyeen" (those exalted). Forgive my sins. Bestow on me such belief that Thou may be nearest to my heart. Give me such an understanding that all the doubts may be removed. Let me be contented with what has been ordained for me. Let me have goodness and virtues in this world and in the next. Save me from the glowing fire of hell. Encourage me to remember Thee with devotion and pleasure and to be penitent. Bless me with virtues that Thou hast bestowed on Muhammads (S.A.W.) and his Aal (A.S.).
