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.
النَّبِيُّ ﷺ اشْتَرِيهَا فَإِنَّمَا الْوَلاَءُ لِمَنْ أَعْطَى الثَّمَنَ أَوْ لِمَنْ وَلِيَ النِّعْمَةَ قَالَ وَفِي الْبَابِ عَنِ ابْنِ عُمَرَ
"The Wala' is for the one who gives the price, or for the one who grants the favor."
النَّبِيُّ ﷺ الْوَلاَءُ لِمَنْ أَعْطَى الثَّمَنَ أَوْ لِمَنْ وَلِيَ النِّعْمَةَ
