Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) said: The Prophet (peace and blessings be upon him) held a walimah after marrying Sayyidah Safiyyah (may Allah be pleased with her). (The narrator said:) I asked: What was there at that walimah? He said: There was nothing but dates and sawiq (barley meal).
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Abd al-Hamid bin Sulayman, and he is da'if (weak), though he has also been declared reliable.
