Sahih Muslim — Hadith #7596

Abu Nadr Hashim bin Qasim narrated a hadith, saying: We heard Abu Aqeel (Yahya bin Mutawakkil), the master of Bahiya, narrate a hadith, saying: I was sitting with Qasim bin Ubaidullah (bin Abdullah bin Umar whose mother was Umm Abdullah bint Qasim bin Muhammad bin Abi Bakr) and Yahya bin Saeed when Yahya said to Qasim bin Ubaidullah: Mr. Abu Muhammad! This is a great fault for a person like you, it is a great matter that you are asked about a matter of this religion and you have no knowledge or solution or (say these words) no knowledge or way out regarding it. So Qasim said to him: For what reason? (Yahya) said: Because you are the son of the two Imams of guidance, Abu Bakr and Umar. He said: Qasim said to him: "For a person who has been given intelligence from Allah, it is worse for me to say something without knowledge or to narrate from someone who is not trustworthy." (On hearing this, Yahya) remained silent and did not answer him.
