عَنْ عُبَيْدِ بْنِ تَعْلَى قَالَ غَزَوْنَا مَعَ عَبْدِ الرَّحْمَنِ بْنِ خَالِدِ بْنِ الْوَلِيدِ فَأُتِيَ بِأَرْبَعَةِ أَعْلَاجٍ مِنَ الْعَدُوِّ فَأَمَرَ بِهِمْ فَقُتِلُوا صَبْرًا بِالنَّبْلِ فَبَلَغَ ذلِكَ أَبَا أَيُّوبَ رَضِيَ اللَّهُ عَنْهُ فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَنْهَى عَنْ قَتْلِ الصَّبْرِ
It is narrated from Ubaid bin Ta'li, he says: We fought a battle under the leadership of Abdur Rahman bin Khalid bin Walid. Four disbelievers from among the non-Arabs were brought to him, and he ordered regarding them, so they were tied up and killed with arrows. When this reached Sayyiduna Abu Ayyub (may Allah be pleased with him), he said: I heard the Messenger of Allah (peace and blessings be upon him) forbidding killing by tying up.
