قَالَ يَحْيَى قَالَ مَالِكٌ عَنْ هِشَامِ بْنِ عُرْوَةَ، أَنَّ عَبْدَ اللَّهِ بْنَ الزُّبَيْرِ، كَانَ يَقْضِي بِشَهَادَةِ الصِّبْيَانِ فِيمَا بَيْنَهُمْ مِنَ الْجِرَاحِ ‏.‏ قَالَ مَالِكٌ الأَمْرُ الْمُجْتَمَعُ عَلَيْهِ عِنْدَنَا أَنَّ شَهَادَةَ الصِّبْيَانِ تَجُوزُ فِيمَا بَيْنَهُمْ مِنَ الْجِرَاحِ وَلاَ تَجُوزُ عَلَى غَيْرِهِمْ وَإِنَّمَا تَجُوزُ شَهَادَتُهُمْ فِيمَا بَيْنَهُمْ مِنَ الْجِرَاحِ وَحْدَهَا لاَ تَجُوزُ فِي غَيْرِ ذَلِكَ إِذَا كَانَ ذَلِكَ قَبْلَ أَنْ يَتَفَرَّقُوا أَوْ يُخَبَّبُوا أَوْ يُعَلَّمُوا فَإِنِ افْتَرَقُوا فَلاَ شَهَادَةَ لَهُمْ إِلاَّ أَنْ يَكُونُوا قَدْ أَشْهَدُوا الْعُدُولَ عَلَى شَهَادَتِهِمْ قَبْلَ أَنْ يَفْتَرِقُوا ‏.‏

Malik said, "The generally agreedon way of doing things in our community is that the testimony ofchildren is permitted concerning injuries between them. It is notaccepted about anything else. It is only permitted between them ifthey testify before they leave the scene of the incident and have beendeceived or instructed. If they leave the scene, they have notestimony unless they call just witnesses to witness their testimonybefore they leave." Translation Not Available
