The narration of Sayyiduna Abu Hurairah (may Allah be pleased with him) in which it was mentioned that: "In terms of sequence among nations, we are the last of all nations, but on the Day of Resurrection, in terms of reckoning and being taken to Paradise, we will be the foremost." has already passed. (See the chapter: The Obligation of Jumu'ah...) At the end of this narration, it is further mentioned that then the Prophet (peace and blessings of Allah be upon him) said: "It is obligatory upon every Muslim to perform ghusl (ritual bath) once a week, on that day he should thoroughly clean his head and his body."
