What did the Prophet Muhammad (saw) say when `Aisha mentioned her intention to buy Barira (peace be upon him)?
 Narrated `Aisha:                     that she intended to buy Barira (a slave girl) and her masters stipulated that they would have her Wala'. When `Aisha mentioned that to the Prophet ; he said, "Buy her, for the Wala' is for the one who manumits."
