It is narrated from Sayyiduna Amr bin Kharijah (may Allah be pleased with him) that he heard the Messenger of Allah (peace and blessings be upon him) say this in his sermon, while he was beneath the neck of his (peace and blessings be upon him) she-camel. Then the narrator related a hadith similar to it, and he did not mention Abd al-Rahman bin Ghanm in it.
