Narrated An-Nu`man bin Bashir: that his father took him to Allah's Apostle and said, "I have given this son of mine a slave." The Prophet asked, "Have you given all your sons the like?" He replied in the negative. The Prophet said, "Take back your gift then."

Narrated 'Amir: I heard An-Nu`man bin Bashir on the pulpit saying, "My father gave me a gift but `Amra bint Rawaha (my mother) said that she would not agree to it unless he made Allah's Apostle as a witness to it. So, my father went to Allah's Apostle and said, 'I have given a gift to my son from `Amra bint Rawaha, but she ordered me to make you as a witness to it, O Allah's Apostle!' Allah's Apostle asked, 'Have you given (the like of it) to everyone of your sons?' He replied in the negative. Allah's Apostle said, 'Be afraid of Allah, and be just to your children.' My father then returned and took back his gift."

Narrated An-Nu`man bin Bashir: My mother asked my father to present me a gift from his property; and he gave it to me after some hesitation. My mother said that she would not be satisfied unless the Prophet was made a witness to it. I being a young boy, my father held me by the hand and took me to the Prophet . He said to the Prophet, "His mother, bint Rawaha, requested me to give this boy a gift." The Prophet said, "Do you have other sons besides him?" He said, "Yes." The Prophet said, "Do not make me a witness for injustice." Narrated Ash-Shu`bi that the Prophet said, "I will not become a witness for injustice."
