It was narrated that Nu'man bin Bashir said that his father took him to the Prophet (ﷺ) and said: “Bear witness that I have given Nu'man such and such from my wealth.” He said: “Have you given all your children something like that which you have given to Nu'man?” He said: “No.” He said: “Then let someone other than me bear witness to that.” And he said: “Would you not like all your children to honor you equally?” He said: “Of course.” He said: “Then do not do this.”
It was narrated from Nu'man bin Bashir that: his father gave him a gift of a slave, and he came to the Prophet (ﷺ) so that he could witness the gift. He said: “Have you given something to all of your children?” He said: “No.” He said: “Then take back (your gift).”
