From 'Aishah that she wanted to purchase Barirah, but they (he owners) made the condition that they would retain the Wala'. So the Prophet (ﷺ) said: "Buy her, the Wala' is only for the one who gives the price, or for the one who grants the favor."

[He said:] There is something on this topic from Ibn 'Umar.

[Abu 'Eisa said:] The Hadith of 'Aishah is a Hasan Sahih Hadith. This is acted upon according to the people of knowledge. And Mansur bin Al-Mu'tamir's Kunyah is Abu 'Attab.

Abu Bakr Al-'Attar Al-Basri narrated to us from 'Ali bin Al-Madini who said: "I heard Yahya bin Sa'eed saying: 'When you get a narration from Mansur, then your hand has been filled with goodness without needing others.' Then Yahya said: 'I did not find anyone more reliable in (narrating from) Ibrahim An-Nakha'i and Mujahid than Mansur."

[He said:] Muhammad informed me from 'Abdullah bin Abi Al-Aswad who said: " 'Abdur-Rahman bin Mahdi said: 'Mansur is the most reliable of the people of Al-Kufah.'"
