Tabarani related it in al-Awsat, Majma al-Bahrayn (1757), from Muhammad bin Husayn Abu Husayn, who said, Abdul-Rahman bin Yunus Raqqi told us, Abdul-Salam bin Harb told us, from Khaseef, from Mujahid, from Ibn Abbas, who said, and then he mentioned it.Its chain is hasan because of Khaseef bin Abdul-Rahman Jazari, for there is disagreement about him, but his hadith is judged hasan when it does not contradict other reports and does not contain anything objectionable. His hadith has a firm basis, and this is one of them.Haythami said in al-Majma (3/251), "Tabarani related it in al-Awsat, and it contains Khaseef, whom Ibn Main and others considered reliable, while Ahmad and others considered him daif."
