The Messenger of Allah (sal Allahu alaihi wa sallam) said: “The best day on which the sun rises is Friday. On this day Adam was created, on this day he came down (from Jannah), it was Friday when his repentance was accepted, and this day he died. The Hour will occur on Friday. There is no creature which is not waiting every Friday, from the moment the sun rises, fearing the Hour – apart from jinn and men.” [Sunan Abi Dawood]
Friday is a significant day for Muslims. It has been important historically and there are many recommended and obligatory deeds that are especially rewarded on Fridays. However, it is also a day feared by all creatures except men and jinn, because of their knowledge that it is a Friday on which the Hour will commence.
