"What did the Prophet Muhammad (saw) say to `Aisha when she wanted to buy a slave-girl and her masters stipulated that her Wala' would be for them?"
 Narrated `Abdullah bin `Umar:                     Aisha wanted to buy a slave-girl in order to manumit her. The girl's masters stipulated that her Wala' would be for them. Allah's Apostle said (to `Aisha), "What they stipulate should not stop you, for the Wala' is for the liberator."
