The last night of the holy month of Ramadhan is a night of many blessings and in which many acts are recommended such as:
First: Have a bath (Ghusl)
Second: Ziyarat Imam al-Hussayn (peace be upon him)
Third: Recite the following Surahs from the Holy Quran: An'aam (Ch6), Al-Kahf (Ch18), Yaseen (Ch 36 ) and 100 times "Astaghfiru Allah wa Atoubou ilayh." I seek the forgiveness of Allah and I repent before Him.
Fourth: Imam Ja'far As-Sadeq (peace be upon him) used to recite the following dua tonight: "O Allah the month of Ramadhan, in which Thou revealed the Holy Quran, now is at its end. I take refuge with Thy kindest disposition, O Lord, lest the dawn of this night breaks forth, or the month of Ramadhan comes to an end, and I stand as an accused sinner, liable to be punished, on the Day I am presented before Thee."
Fifth: Recite the following Dua: "O the Director of all affairs; O the Resurrector of all those in graves; O He Who causes oceans to flow; O He Who made the iron pliant for (Prophet) David; (Please) pray upon Mohammad and the Household of Mohammad…"
Sixth: Recite Duaa-e-Widaa’a ie Bidding Farewell
a- by Imam Ja'far As-Sadeq (peace be upon him): "O Allah: (please) do not decide my observance of fasting in this month of Ramadhan to be the last of my (life's) observance of fasting. I take refuge with Thee lest the dawn of this night breaks forth without me having been positively forgiven."
b- Sayed ibn Tawous and Kaf’ami reports that the Holy Prophet (S.A.) had advised to pray a 10 Rak-a’t Salaat, in 5 sets of two Rak-a’t each, on the last night of this month, as under:-
(i) In every Rak-a’t, after the recitation of Surah Al Faatih’ah, recite Soorah Al Ikhlaas 10 times.
(ii) In every “Ruku’” and “Sajdah” recite the four Tasbihat following 10 times: "All glory be to Allah; all praise be to Allah; there is no god save Allah; Allah is the Greatest."
After each 2 Rak`ahs, one may recite the Tashahhud and Tasleem. After the accomplishment of the ten Rak`ahs, one may recite the Tasleem and say the following one thousand times: "I seek the forgiveness of Allah and I repent before Him."
After that, one may prostrate and say the following:
"O Ever-Alive, O Eternal, O the Lord of Majesty and Honor. O the All-beneficent of this world and the Next World and the All-merciful of them; O the most Merciful of all those who show mercy. O the God of the past and the coming generations; (Please) forgive us our sins, And accept our prayers, fasting, and worship."
The Holy Prophet (Allah's prayers be upon him and upon his holy Household) then continues, “I swear by Him Who has sent me with the truth as Prophet; Archangel Gabriel has reported to me from Archangel Israfel who directly reports from Almighty Allah that one who offers that prayer will not raise his head from prostration before Almighty Allah would forgive him, accept his acts during the month of Ramadhan, and overlooks his sins... .”
c- Sayyid Ibn Tawus and Shaykh al-Saduq have both narrated the following on the authority of Jabir ibn `Abdullah al-Ansari: I visited the Messenger of Allah (Allah's prayers be upon him and upon his holy Household) on the last Friday of the month of Ramadhan. As he saw me, he said, “Jabir: This is the last Friday of the month of Ramadhan. You should thus bid it farewell by saying the following: "O Allah: (please) do not make it the last of our fasting in this month; but if You decide so, then (please) make me enjoy (Your) mercy and do not make me deprived (of it)."
Verily, anyone who says this supplication will win one of the two good things; either attaining the next month of Ramadhan or having the forgiveness and mercy of Almighty Allah.”
d- Recite Dua by Imam as-Sajjad (peace be upon him) from Sahifa Sajjadia.
Seventh: Usually the recitation of the Holy Quran is completed tonight and therefore it is recommended to recite the Dua of completion of the recitation of all the holy Quran stated in Sahifa sajjadia number forty two.
