Abu al-Mughirah al-Thaqafi (may Allah have mercy on him) says that his father told him that he was with his father at Mina, and he heard a caller announcing: O people, load the baggage onto the mounts last, for the feet are firm and the hands hang loose. I said to my father: Who is this? He said: This is Sayyiduna Umar (may Allah be pleased with him).
Ya'qub said: Maslamah is a Kufan, thiqah (trustworthy). A musnad hadith has been narrated on this with a chain that is not strong.
