أَخْبَرَنَا أَبُو ظَبْيَانَ، قَالَ سَمِعْتُ أُسَامَةَ بْنَ زَيْدٍ رضى الله عنهما يَقُولُ بَعَثَنَا رَسُولُ صلّى الله عليه وسلّم إِلَى الْحُرَقَةِ، فَصَبَّحْنَا الْقَوْمَ فَهَزَمْنَاهُمْ وَلَحِقْتُ أَنَا وَرَجُلٌ مِنَ الأَنْصَارِ رَجُلاً مِنْهُمْ، فَلَمَّا غَشِينَاهُ قَالَ لاَ إِلَهَ إِلاَّ الله. فَكَفَّ الأَنْصَارِيُّ، فَطَعَنْتُهُ بِرُمْحِي حَتَّى قَتَلْتُهُ، فَلَمَّا قَدِمْنَا بَلَغَ النَّبِيَّ صلّى الله عليه وسلّم فَقَالَ يَا أُسَامَةُ أَقَتَلْتَهُ بَعْدَ مَا قَالَ لاَ إِلَهَ إِلاَّ الله قُلْتُ كَانَ مُتَعَوِّذًا. فَمَا زَالَ يُكَرِّرُهَا حَتَّى تَمَنَّيْتُ أَنِّي لَمْ أَكُنْ أَسْلَمْتُ قَبْلَ ذَلِكَ الْيَوْمِ.
Abu Zabyan [Husayn ibn Jundub] informed us that “I heard from Usama ibn Zaydra, who said, ‘The Messengersa sent us towards [the tribe of] Al-Huruqah. We attacked them at dawn, defeating and driving them away. An Ansari man and I pursued one of their men. When we cornered him, he exclaimed, ‘La ilaha illAllah’ [There is no god but Allah]. Hearing this, the Ansari halted, but I struck him with my spear and killed him. When we returned and the incident was reported to the Prophetsa, he said, ‘O Usama! Did you kill him after he had said, ‘La ilaha illAllah’?’ I replied, he said it only to protect himself. However, he repeated [his question] so often that I wished I had not become a Muslim before that day.’”
