(Another chain) From Ibn 'Umar: A man came to the Prophet (ﷺ) and said: "O Messenger of Allah! I have been afflicted by a tremendous sin. Is there any repentance for me?" He said: "Do you have your mother?" The man said: "No." He said: "Do you have any maternal aunts?" The man said: "Yes." He said: "Then be dutiful to them."
