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."
Jami` at-Tirmidhi Book 27, Hadith 9
← Previous Hadith the Prophet said: "The maternal aunt holds the same status as the mother."

Jami` at-Tirmidhi Book 27, Hadith 8 Next Hadith → (Another chain) From Abu Bakr bin Hafs, from the Prophet (ﷺ), and it is similar, but he did not mention "from Ibn `Umar" in it. This is more correct than the Hadith of Abu Mu'awiyah, and Abu Bakr bin Hafs is Ibn 'Umar bin Sa'd bin Abi Waqqas (narrators in the chain of this Hadith.)
