It is narrated from Sayyiduna Abu Humayd al-Sa'idi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) set out (from Madinah) on the day of the Battle of Uhud, until, when he (peace and blessings be upon him) had gone beyond the place called Thaniyyat al-Wada', he (peace and blessings be upon him) looked back and saw a formidable, heavily armed military unit there. He (peace and blessings be upon him) asked: "Who are these people?" It was said: "This is Abdullah bin Ubayy bin Salul with his Jewish allies of Banu Qaynuqa', and these are the people of Abdullah bin Salam's clan." He (peace and blessings be upon him) asked: "Have these people accepted Islam?" It was said: "No, rather they remain on their own religion." So he (peace and blessings be upon him) said: "Tell them to go back, for we never seek help from polytheists against polytheists."
This chain is hasan (good).
