نَا عَلِيُّ بْنُ مُحَمَّدِ بْنِ أَحْمَدَ الْمِصْرِيُّ ، نَا يَحْيَى بْنُ عُثْمَانَ بْنِ صَالِحٍ ، عَنْ عَلِيِّ بْنِ مَعْبَدٍ ، نَا عَمْرُو بْنُ هَاشِمٍ ، عَنْ مُحَمَّدِ بْنِ عَجْلانَ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ، أَنَّهُ دَعَاهُ رَجُلٌ فَأَشْهَدَهُ عَلَى وَصِيَّةٍ فَإِذَا هُوَ قَدْ آثَرَ بَعْضَ وَلَدِهِ عَلَى بَعْضٍ ، فَقَالَ عَبْدُ اللَّهِ بْنُ عُمَرَ : " نَهَانَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ نَشْهَدَ عَلَى جَوْرٍ ، وَقَالَ : مَنْ شَهِدَ عَلَى جَوْرٍ فَهُوَ شَاهِدُ زُورٍ ، ثُمَّ أَسْرَعَ الْمَشْيَ " .
It is narrated about Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that a man called him and wanted to make him a witness regarding his will, and in that will he had given preference to some of his children over others. So Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) said: The Noble Prophet (peace and blessings be upon him) has forbidden us from being witnesses to an act of injustice. He said: "Whoever becomes a witness to an act of injustice is like a false witness." Then Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) quickly walked away.
