Jami` at-Tirmidhi Book 27, Hadith 10
(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.)
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."
"Three supplications are accepted , there is no doubt in them (about them being accepted): The supplication of the oppressed, the supplication of the traveler, and the supplication of his father against his son."
