[Machine] We sent the Messenger of Allah ﷺ to Itham. I went out with a group of Muslims, including Abu Qatadah Al-Harith ibn Rib'iyy and Muhalib ibn Jathama ibn Qays. We went out until, when we were in the valley of Itham, 'Amir Al-Ashja'i passed by us on his camel. He had with him a sheep, a container of milk, and dates. When he passed by us, he greeted us, but we restrained him. Muhalib ibn Jathama attacked him with something he had, which resulted in his death. Muhalib also took his camel, sheep, and dates. When we arrived to the Messenger of Allah ﷺ and informed him of the news, the following verse from the Quran was revealed: "O you who have believed, when you go forth [to fight] in the cause of Allah , investigate; and do not say to one who gives you [a greeting of] peace "You are not a believer," aspiring for the goods of worldly life; for with Allah are many acquisitions. You [yourselves] were like that before; then Allah conferred His favor upon you, so investigate. Indeed Allah is ever, with what you do, Acquainted." (4:94) [Surah An-Nisa]  

بَعَثَنَا رَسُولُ اللهِ ﷺ إِلَى إِضَمَ فَخَرَجْتُ فِي نَفَرٍ مِنَ الْمُسْلِمِينَ فِيهِمْ أَبُو قَتَادَةَ الْحَارِثُ بْنُ رِبْعِيٍّ وَمُحَلَّمُ بْنُ جَثَّامَةَ بْنِ قَيْسٍ فَخَرَجْنَا حَتَّى إِذَا كُنَّا بِبَطْنِ إِضَمَ مَرَّ بِنَا عَامِرٌ الْأَشْجَعِيُّ عَلَى قَعُودٍ لَهُ مَعَهُ مُتَيِّعٌ وَوَطْبٌ مِنْ لَبَنٍ فَلَمَّا مَرَّ بِنَا سَلَّمَ عَلَيْنَا فَأَمْسَكْنَا عَنْهُ وَحَمَلَ عَلَيْهِ مُحَلَّمُ بْنُ جَثَّامَةَ فَقَتَلَهُ بِشَيْءٍ كَانَ بَيْنَهُ وَبَيْنَهُ وَأَخَذَ بَعِيرَهُ وَمُتَيِّعَهُ فَلَمَّا قَدِمْنَا عَلَى رَسُولِ اللهِ ﷺ وَأَخْبَرْنَاهُ الْخَبَرَ نَزَلَ فِينَا الْقُرْآنُ {يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا ضَرَبْتُمْ فِي سَبِيلِ اللهِ فَتَبَيَّنُوا وَلَا تَقُولُوا لِمَنْ أَلْقَى إِلَيْكُمُ السَّلَامَ لَسْتَ مُؤْمِنًا تَبْتَغُونَ عَرَضَ الْحَيَاةِ الدُّنْيَا فَعِنْدَ اللهِ مَغَانِمُ كَثِيرَةٌ كَذَلِكَ كُنْتُمْ مِنْ قَبْلُ فَمَنَّ اللهُ عَلَيْكُمْ فَتَبَيَّنُوا إِنَّ اللهَ كَانَ بِمَا تَعْمَلُونَ خَبِيرًا} [النساء 94]
