Hazrat Bahz bin Hakim narrates from his father, from his grandfather (Sayyiduna Mu'awiyah bin Haydah, may Allah be pleased with him) that he said: I asked, "O Messenger of Allah! With whom should I show good conduct?" The Prophet (peace and blessings be upon him) said, "Your mother." I said, "(Then) with whom should I show good conduct?" The Prophet (peace and blessings be upon him) said, "Your mother." I said, "Then with whom should I show good conduct?" The Prophet (peace and blessings be upon him) said, "Your mother." I said, "Then with whom should I show good conduct?" The Prophet (peace and blessings be upon him) said, "Your father, then the next closest relative to you, then the next closest after that."

Hazrat Ata bin Yasar (may Allah have mercy on him) narrates from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that a man came to him and said: I sent a marriage proposal to a woman, but she refused to marry me. Then someone else, other than me, sent her a marriage proposal and she agreed. I became jealous over this and killed her. Is there any way for me to repent? (Sayyiduna Ibn Abbas, may Allah be pleased with them both) said: Is your mother alive? He replied: No. Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: Repent to Allah and seek closeness to Allah as much as you can (through righteous deeds, etc.). (The narrator of the hadith, Hazrat Ata, may Allah have mercy on him, says) I went to Sayyiduna Ibn Abbas (may Allah be pleased with them both) and asked him: Why did you ask him whether his mother was alive? He replied: In my knowledge, there is no deed that brings a person closer to Allah than showing kindness to the mother.
