3-182 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Sa’ed ibn Abdullah quoted Ahmad ibn Aba Abdullah Al-Barqy, on the authority of Ahmad ibn Muhammad ibn Abi Nasr al-Bazanty, on the authority of Hammad ibn Uthman, on the authority of Abdullah ibn Abi Ya’fur that Aba Abdullah as-Sadiq (MGB) said,

“Once during the Last Pilgrimage to Mecca the Prophet of God (MGB) delivered a sermon in the Al-Khayf Mosque of Mina. He (MGB) started out by saying God’s Praises and His Glorifications. Then the Prophet (MGB) added, “May God assist any servant who hears me, remembers what I say and delivers it to whoever has not heard it. There are many who utter what they do not understand, but there are listeners who benefit from what they have said. There are many knowledgeable ones who state things for people of a better understanding and they benefit more from what is said. There are three things which a Muslim’s heart doesn’t doubt: having sincerity in what you do for the sake of God; being united with the nation’s leaders; and being associated with the Muslims, since inviting the Muslims includes anyone who supports them. Muslims are brothers one to another and their blood is all of the same color. Even the pledge of their youngest one is binding upon them all. All Muslims are united together against their enemies.”
