Sayyiduna Abd al-Muttalib bin Rabi'ah bin al-Harith (may Allah be pleased with him) said: Sayyiduna al-Abbas (may Allah be pleased with him) sent his son al-Fadl, and my father Rabi'ah bin al-Harith sent me. We set off until we came to the Messenger of Allah (peace and blessings be upon him); then the narrator mentioned a similar hadith.
Sayyiduna al-Muttalib bin Abi Wada'ah (may Allah be pleased with him) said: "I saw the Messenger of Allah (peace and blessings be upon him)" prostrate in Surah al-Najm, and the people prostrated with him. Al-Muttalib said: "I did not prostrate with them" - he was a polytheist at that time - al-Muttalib said: "So I will never leave prostrating in it."
