It is narrated from Sayyiduna Ibn Amr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "One of the major sins is that a man abuses his parents." The people asked, "O Messenger of Allah! How can a man abuse his own parents?" The Prophet (peace and blessings be upon him) said: "He abuses another man's father, and that man in return abuses his father; and he abuses another man's mother, and that man in return abuses his mother."
