´Abu Bakr bin Hafs - and he is Ibn Umar bin Sa'd bin Abi Waqas - narrated about Ibn Umar, that:` "He went out on the day of Eid, and he did not pray before it nor after it. He mentioned that the Prophet did so."

´It is narrated from Abdullah bin Umar (may Allah be pleased with them both) that` a man came to the service of the Prophet Muhammad (peace be upon him) and said: O Messenger of Allah! A very great sin has been committed by me, is there any room for repentance for me? He asked: "Is your mother alive?" He said: No. He asked: Do you have a maternal aunt? He said: Yes. He said: "Treat her kindly." © Imam Tirmidhi says:
1- In this chapter, ahadith have also been narrated from Ali and Bara bin Azib (may Allah be pleased with them).

With this chain, a similar hadith is narrated from the Prophet Muhammad (peace be upon him), but in it, the mention of the intermediary of Ibn Umar is not included; this narration is more authentic than the hadith of Abu Muawiyah.
