Sahih al-Bukhari 2650
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 (ﷺ) was made a witness to it. 
I being a young boy, my father held me by the hand and took me to the Prophet (ﷺ) . He said to the 
Prophet, "His mother, bint Rawaha, requested me to give this boy a gift." The Prophet (ﷺ) said, "Do you 
have other sons besides him?" He said, "Yes." The Prophet (ﷺ) said, "Do not make me a witness for 
injustice." Narrated Ash-Shu`bi that the Prophet (ﷺ) said, "I will not become a witness for injustice."
حَدَّثَنَا عَبْدَانُ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا أَبُو حَيَّانَ التَّيْمِيُّ، عَنِ الشَّعْبِيِّ، عَنِ النُّعْمَانِ بْنِ بَشِيرٍ ـ رضى الله عنهما ـ قَالَ سَأَلَتْ أُمِّي أَبِي بَعْضَ الْمَوْهِبَةِ لِي مِنْ مَالِهِ، ثُمَّ بَدَا لَهُ فَوَهَبَهَا لِي فَقَالَتْ لاَ أَرْضَى حَتَّى تُشْهِدَ النَّبِيَّ صلى الله عليه وسلم‏.‏ فَأَخَذَ بِيَدِي وَأَنَا غُلاَمٌ، فَأَتَى بِيَ النَّبِيَّ صلى الله عليه وسلم فَقَالَ إِنَّ أُمَّهُ بِنْتَ رَوَاحَةَ سَأَلَتْنِي بَعْضَ الْمَوْهِبَةِ لِهَذَا، قَالَ ‏"‏ أَلَكَ وَلَدٌ سِوَاهُ ‏"‏‏.‏ قَالَ نَعَمْ‏.‏ قَالَ فَأُرَاهُ قَالَ ‏"‏ لاَ تُشْهِدْنِي عَلَى جَوْرٍ ‏"‏‏.‏ وَقَالَ أَبُو حَرِيزٍ عَنِ الشَّعْبِيِّ ‏"‏ لاَ أَشْهَدُ عَلَى جَوْرٍ ‏"‏‏.‏
