It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, who says: The Messenger of Allah, peace and blessings be upon him, said to me: O Bilal! Tell me about the most hopeful deed of yours, which, in your opinion, is the most beneficial in Islam, because I heard the sound of your shoes ahead of me in Paradise last night? Sayyiduna Bilal, may Allah be pleased with him, said: I have not done any such deed which, in my view, is the most hopeful in terms of benefit in Islam, except (this deed that) whenever I perform ablution at any hour of the night or day, I offer as much prayer with that ablution as Allah Almighty has destined for me.
