It is narrated from Sayyiduna Usama bin Zaid (may Allah be pleased with them both) that the Prophet (peace and blessings of Allah be upon him) rode on a donkey on whose saddle there was a sheet made in Fadak, and he (peace be upon him) seated Usama bin Zaid behind him. The Prophet (peace be upon him) went to visit Sayyiduna Sa’d bin ‘Ubadah (may Allah be pleased with him) to inquire about his health, until he (peace be upon him) passed by a gathering in which ‘Abdullah bin Ubayy bin Salul was also present. This incident occurred before this enemy of Allah had outwardly accepted Islam. In the gathering, there were Muslims, polytheists, and idolaters mixed together. The Prophet (peace be upon him) greeted them with salam.
