Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) narrates that when Sayyiduna Abu Usayd (may Allah be pleased with him) got married, he invited the Prophet (peace and blessings be upon him) and the Companions (may Allah be pleased with them) to the feast. The guests' food was prepared and served by his wife. During the night she had soaked some dates in a pot, and when he (peace and blessings be upon him) had finished, she offered that water to him (peace and blessings be upon him), and he (peace and blessings be upon him) drank it.
