Translation: Hadhrat Anas bin Malik (May Allah be well pleased with him) relates from the Holy Prophet (Sallallahu alaihi wa sallam) that He (Sallallahu alaihi wa sallam) said: There is such a night in the month of Rajab in which virtues worth 100 years are written for those who act and that is the 27th night of Rajab. The person who offers 12 Raka’at of Salaat this night in such a way that he (or she) recites any Surah after Surah Fatiha, in units of 2 Raka’at each and after finishing the Salaat, recites Subhan Allahi Walhamdulillahi Wa Laa Ilaaha Illallahu Wallaahu Akbar 100 times, recites “Istighfaar” 100 times and sends Durood on the Holy Prophet (Sallallahu alaihi wa sallam) 100 times and asks for whatever good he (or she) wants of this world or the hereafter and fasts the next day, Almighty Allah will certainly accept all his supplications except that he makes supplicates for some disobedience (that supplication will not be accepted).
