Abu Salih, who was the freed slave of Sayyiduna Uthman (may Allah be pleased with him), says: I heard Sayyiduna Uthman (may Allah be pleased with him) saying from the pulpit during a sermon: O people! Until now, I have not narrated to you a hadith that I heard from the Prophet (peace and blessings be upon him) so that you would not separate from me, but now I consider it appropriate to narrate it to you so that every person may choose as he sees fit. I heard the Prophet (peace and blessings be upon him) say: Standing guard for one day in the path of Allah is better than standing guard for a thousand days in other places.
