Translation
Narrated `Abdul Wahid bin Aiman:I went to `Aisha and said, "I was the slave of `Utba bin Abu Lahab. "Utba died and his sons became my masters who sold me to Ibn Abu `Amr who manumitted me. The sons of `Utba stipulated that my Wala' should be for them." `Aisha said, "Barirah came to me and she was given the writing of emancipation by her masters and she asked me to buy and manumit her. I agreed to it, but Barirah told me that her masters would not sell her unless her Wala' was for them." `Aisha said, "I am not in need of that." When the Prophet (ﷺ) heard that, or he was told about it, he asked `Aisha about it. `Aisha mentioned what Barirah had told her. The Prophet (ﷺ) said, "Buy and manumit (free) her and let them stipulate whatever they like." So, `Aisha bought and manumitted her and her masters stipulated that her Wala' should be for them." The Prophet;, said, "The Wala' will be for the liberator even if they stipulated a hundred conditions
