It is narrated from Sayyiduna Sulayman bin Surad (may Allah be pleased with him); he said: The Messenger of Allah (peace and blessings be upon him) came to us and stayed for three nights, and we were not able to provide food, or (the narrator said, in doubt) we were not able to provide. Abdullah bin Ahmad said: I mentioned this hadith to my father (Imam Ahmad, may Allah have mercy on him), and he approved of it.
