Abdullah bin Abi Hamsa (may Allah be pleased with him) narrates: Before the declaration of Prophethood, I bought something from the Prophet (peace and blessings be upon him), and there was some payment left that I owed him. I promised to bring the remaining amount to him at that same place, but I forgot. After three days, I remembered (and went), and he was still at that place. The Prophet (peace and blessings be upon him) said: "You put me through hardship; I have been waiting for you here for three days." Its chain is weak. Narrated by Abu Dawood.
