Messenger of Allah ﷺ sent us (to fight) against Al-Huraqa (one of the sub-tribes) of Juhaina. We reached those people in the morning and defeated them. A man from the Ansar and I chased one of their men and when we attacked him, he said, "None has the right to be worshipped but Allah." The Ansari refrained from killing him but I stabbed him with my spear till I killed him. When we reached (Medina), this news reached the Prophet. He said to me, "O Usama! You killed him after he had said, 'None has the right to be worshipped but Allah?"' I said, "O Messenger of Allah ﷺ! He said so in order to save himself." The Prophet ﷺ said, "You killed him after he had said, 'None has the right to be worshipped but Allah." The Prophet ﷺ kept on repeating that statement till I wished I had not been a Muslim before that day.  

بَعَثَنَا رَسُولُ اللَّهِ ﷺ إِلَى الْحُرَقَةِ مِنْ جُهَيْنَةَ قَالَ فَصَبَّحْنَا الْقَوْمَ فَهَزَمْنَاهُمْ قَالَ وَلَحِقْتُ أَنَا وَرَجُلٌ مِنَ الأَنْصَارِ رَجُلاً مِنْهُمْ قَالَ فَلَمَّا غَشِينَاهُ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ قَالَ فَكَفَّ عَنْهُ الأَنْصَارِيُّ فَطَعَنْتُهُ بِرُمْحِي حَتَّى قَتَلْتُهُ قَالَ فَلَمَّا قَدِمْنَا بَلَغَ ذَلِكَ النَّبِيَّ ﷺ قَالَ فَقَالَ لِي يَا أُسَامَةُ أَقَتَلْتَهُ بَعْدَ مَا قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّمَا كَانَ مُتَعَوِّذًا قَالَ أَقَتَلْتَهُ بَعْدَ أَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ قَالَ فَمَا زَالَ يُكَرِّرُهَا عَلَىَّ حَتَّى تَمَنَّيْتُ أَنِّي لَمْ أَكُنْ أَسْلَمْتُ قَبْلَ ذَلِكَ الْيَوْمِ  

The Messenger of Allah may peace be upon him) sent us to Huraqat, a tribe of Juhaina. We attacked that tribe early in the morning and defeated them and I and a man from the Ansar caught hold of a person (of the defeated tribe). When we overcame him, he said: There is no god but Allah. At that moment the Ansari spared him, but I attacked him with my spear and killed him. The news had already reached the Apostle (peace be upon him), so when we came back he (the Apostle) said to me: Usama, did you kill him after he had made the profession: There is no god but Allah? I said. Messenger of Allah, he did it only as a shelter. The Prophet observed: Did you kill him after he had made the profession that there is no god but Allah? He (the Holy Prophet) went on repeating this to me till I wished I had not embraced Islam before that day.  

بَعَثَنَا رَسُولُ اللَّهِ ﷺ إِلَى الْحُرَقَةِ مِنْ جُهَيْنَةَ فَصَبَّحْنَا الْقَوْمَ فَهَزَمْنَاهُمْ وَلَحِقْتُ أَنَا وَرَجُلٌ مِنَ الأَنْصَارِ رَجُلاً مِنْهُمْ فَلَمَّا غَشَيْنَاهُ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ فَكَفَّ عَنْهُ الأَنْصَارِيُّ وَطَعَنْتُهُ بِرُمْحِي حَتَّى قَتَلْتُهُ قَالَ فَلَمَّا قَدِمْنَا بَلَغَ ذَلِكَ النَّبِيَّ ﷺ فَقَالَ لِي يَا أُسَامَةُ أَقَتَلْتَهُ بَعْدَ مَا قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّمَا كَانَ مُتَعَوِّذًا قَالَ فَقَالَ أَقَتَلْتَهُ بَعْدَ مَا قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ قَالَ فَمَازَالَ يُكَرِّرُهَا عَلَىَّ حَتَّى تَمَنَّيْتُ أَنِّي لَمْ أَكُنْ أَسْلَمْتُ قَبْلَ ذَلِكَ الْيَوْمِ  

[Machine] We sent the Messenger of Allah ﷺ to Al-Hurqah from the tribe of Juheinah. He said, "We attacked them in the morning and fought against them. Among them was a man who, when the enemy approached, was the bravest among them against us. But when they turned their backs, he became their protector." He said, "I and a man from the Ansar overwhelmed him." When we overwhelmed him, he said, "There is no god but Allah." The Ansari hesitated and I killed him. When the Prophet ﷺ was informed about this, he said, "O Usama! Did you kill him after he said, 'There is no god but Allah'?" I said, "O Messenger of Allah! He only said it to protect himself from being killed." The Prophet ﷺ repeated, "Did you kill him after he said, 'There is no god but Allah'?" I said it again, "O Messenger of Allah! He only said it to protect himself from being killed."

[Machine] We sent the Messenger of Allah in an army to Al-Hurqat, a neighborhood of Juheina. When we were about to defeat them, a man from the Ansar (helpers) and I approached a man from them and he said, "There is no god but Allah." The Ansari stopped attacking him, and I thought that he said it to seek refuge, so I killed him. The Ansari then returned to the Prophet and informed him about it. The Prophet said to Osama, "O Osama, did you kill him after he said, 'There is no god but Allah'? How will you then deal with 'There is no god but Allah' on the Day of Judgment?" He kept repeating these words until I wished that I had not embraced Islam before that day.  

بَعَثَنَا رَسُولُ اللهِ ﷺ فِي جَيْشٍ إِلَى الْحُرُقَاتِ حَيٍّ مِنْ جُهَيْنَةَ فَلَمَّا يَعْنِي هَزَمْنَاهُمِ ابْتَدَرْتُ أَنَا وَرَجُلٌ مِنَ الْأَنْصَارِ رَجُلًا مِنْهُمْ فَقَالَ لَا إِلَهَ إِلَّا اللهُ فَكَفَّ عَنْهُ الْأَنْصَارِيُّ وَظَنَنْتُ أَنَّهُ إِنَّمَا قَالَهَا تَعَوُّذًا فَقَتَلْتُهُ فَرَجَعَ الْأَنْصَارِيُّ إِلَى النَّبِيِّ ﷺ فَحَدَّثَهُ الْحَدِيثَ فَقَالَ النَّبِيُّ ﷺ يَا أُسَامَةُ قَتَلْتَ رَجُلًا بَعْدَ أَنْ قَالَ «لَا إِلَهَ إِلَّا اللهُ؟ كَيْفَ تَصْنَعُ بِلَا إِلَهَ إِلَّا اللهُ يَوْمَ الْقِيَامَةِ؟» فَمَا زَالَ يَقُولُ ذَلِكَ حَتَّى وَدِدْتُ أَنِّي لَمْ أَكُنْ أَسْلَمْتُ إِلَّا يَوْمَئِذٍ
