HYPOCRITES AND THE DAWN AND NIGHT PRAYER H 1090 "Hypocrites find no prayer so burdensome as the dawn and the night prayers and yet if they knew their benefits they would come to them even if they had to crawl." R 1090 Bukhari and Muslim with a chain up to Abu Hurairah who related that the Messenger of Allah, praise and peace be upon him, said this.
