Musnad Ahmad 83:2

Ibrahim ibn Khalid narrated to us, Rabah narrated to us, from Ma'mar, from Ibn Tawus, from 'Ikrimah ibn Khalid, from Ja'far ibn al-Muttalib ibn Abi Wada'ah al-Sahmi, from his father, who said: "The Messenger of Allah (peace and blessings of Allah be upon him) recited Surah an-Najm in Makkah, so he prostrated, and those who were with him prostrated. I raised my head and refused to prostrate. Al-Muttalib had not yet embraced Islam on that day, and he would not hear anyone recite it afterward without prostrating."
