A man from the Ansar was in need, so his family said to him, "Go to the Prophet ﷺ and ask him."He went to him while the Prophet ﷺ was delivering a sermon, in which he was saying, "Whoever seeks to abstain from asking, Allah will grant him chastity. Whoever seeks to be self-sufficient, Allah will enrich him. And whoever asks us and we have something to give, we will give him."So the man left without asking.
أن رجلا من الأنصار كانت به حاجة، فقال له أهله: اثت النبي ﷺ فاسأله، فأتاه وهو يخطب وهو يقول: من استعف أعفه الله، ومن استغنى أغناه الله، ومن سألنا فوجدنا له أعطيناه قال: فذهب ولم يسأل.
Imam Ahmad (10989) narrated it from Hushaym, who said, Abu Bishr narrated to us, from Abu Nadra, from Abu Saeed, and he mentioned it. Its chain of transmission is sahih. Abu Bishr is Jafar bin Iyas, one of the narrators found in both Sahih Bukhari and Sahih Muslim. Abu Nadra is Munzir bin Malik bin Qita, with the qaf vowelled with damma and the plain letter with fatha, the Awqi, with the plain letter and the waw vowelled with fatha followed by a qaf, a trustworthy narrator among the narrators of Sahih Muslim. In the hadith that follows, this questioner is mentioned by name as Abu Saeed Khudri himself, who is the one who went to the Prophet ﷺ to ask him.
