Qadr Night

QADR NIGHT is a night in the blessed month of Ramadan. Imam-i Shafi'i [1] noted that it was most probably the seventeenth night, while Imam-i a'zam Abu Hanifa said that the most probable night was the twenty-seventh. We have been told to look for it between the twentieth and the thirtieth nights. It is the most valuable night praised in the Qur'an. The Qur'an began to be revealed to Rasulullah on this night.

[1] imam: i) profound 'alim; founder of a madhhab; ii) leader in congregational salat; iii) caliph.
