It had been the practice of the Prophet (salallahu alayhi wasallam) that he would not sleep in the night preceding the day of Eid-ul-fitr. This night has been named in a Hadith as the Night of Reward (Lailatul Jaiza). Almighty bestows his rewards on those who have spent the month of Ramadan abiding by the dictates of Shari'ah, and all their prayers in this night are accepted. Therefore, it is desirable to perform nafl prayers in this night. The Prophet (salallahu alayhi wasallam) is reported to have said:
To benefit from this opportunity, one should perform as much worship in this night as he can, and should pray for all his needs and desires.
