Sahih al-Bukhari, Hadith 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 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."

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 ‏"‏‏.‏
