Abdullah bin Amir al-Yahsubi (may Allah have mercy on him) says: I heard Sayyiduna Mu'awiyah (may Allah be pleased with him) say on the pulpit in Damascus: O people! Beware of (narrating) the hadiths of the Messenger of Allah (peace and blessings be upon him), except a hadith that used to be mentioned in the time of Sayyiduna Umar (may Allah be pleased with him), for Sayyiduna Umar (may Allah be pleased with him) was a man who made people fear in the matter of Allah. Then I heard him say: Listen! I heard the Messenger of Allah (peace and blessings be upon him) say: "Whomever Allah intends good for, He grants him understanding of the religion."
Listen! And I heard him (peace and blessings be upon him) say: "I am only a treasurer; it is Allah who gives. So whoever I give something to with a willing heart, it is blessed for him, and whoever I give something to because he asked, his example is that of one who eats but is never satisfied."
Listen! And I heard the Messenger of Allah (peace and blessings be upon him) say: "A group from my Ummah will always remain steadfast upon the religion of Allah; those who oppose them or abandon them will not be able to harm them, until the command of Allah comes while they are dominant over the people."
