‘A'isha reported God’s Messenger as saying, “When one of you dozes while praying he should fall over till he has slept enough, for when one of you prays while dozing he does not know whether he may be asking pardon and vilifying himself.
Abu Huraira reported God’s Messenger as saying, “The religion is ease, but if anyone overdoes it it gets the better of him; so keep to the right course, approximate to perfection, rejoice, and ask help in the morning, the evening, and some of the latter part of the night.”
