What did the Prophet Muhammad (saw) advise `Aisha to do when her slave girl's masters stipulated that her Wala' would be for them?
 Narrated `Abdullah bin `Umar:                     Aisha, (mother of the faithful believers) wanted to buy a slave girl and manumit her, but her masters said that they would sell her only on the condition that her Wala' would be for them. `Aisha told Allah's Apostle of that. He said, "What they stipulate should not hinder you from buying her, as the Wala' is for the manumitted."
