It is narrated from Abu Hurayrah (may Allah be pleased with him) that a man asked the Prophet (peace and blessings be upon him): O Messenger of Allah (peace and blessings be upon him)! Who among people has the most right to my good treatment? He said: "Your mother." He asked: Then who? He said: "Then your mother." He asked: Then who? He said: "Then your mother." He asked: Then who? He said: "Then your father." Both of them recorded it in the Sahih from the hadith of Ibn Shubrumah.
