This blessed night of Laylat-ul-Barat has so many virtues. Aisha (may Allah be pleased with her) states: "One night I awoke to find that Rasoolullah sallallahu alayhi wasallam was not by my side. I got very worried, so I got up and noticed that he was in prostration and he stayed there for a very long time. When he got up he said Oh Aisha, do you know what night this is? I replied "Allah and his Rasool know best what night it is." Rasoolullah sallallahu alayhi wasallam then stated "This is Laylat-ul-Barat, this is the fifteenth of Sha'baan, a very great night. In this night you should be attentive in the worship of Allah, for this is the night of accounting. Whichever child is to be born during the coming year is written down on the list on this night, and the name of whoever is going to pass away in the coming year is deleted from the list."
