(3) باب كَرَاهَةِ تَفْضِيلِ بَعْضِ الأَوْلاَدِ فِي الْهِبَةِ
Nu'man b. Bashir reported:
My father brought me to Allah's Messenger (ﷺ) and said: I have donated this slave to my son. whereupon he said: Have you made (such) donation to every one or your sons? He said: No. Thereupon he (the-Holy Prophet) said: Then take him back.
