What did the Prophet Muhammad (saw) say when Bashir's father asked him to witness the gift he was offering to his son?
 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."
