ذِكْرُ الْإِخْبَارِ عَنْ وَصْفِ الشَّيْءِ الَّذِي يُسْتَدَلُّ بِهِ عَلَى مُرُوقِ أَهْلِ النَّهْرَوَانِ مِنَ الْإِسْلَامِ
When we were in the company of the Messenger of Allah ﷺ and he was distributing the spoils of war, there came to him Dhul-Khuwasira, one of Banu Tamim. He said: Messenger of Allah, do justice. Upon this the Messenger of Allah ﷺ said: Woe be upon thee! Who would do justice, if I do not do justice? You would be unsuccessful and incurring a loss, if I do not do justice. Upon this Umar b. Khattab (Allah be pleased with him) said: Messenger of Allah, permit me to strike off his neck. The Messenger of Allah ﷺ said: Leave him, for he has friends (who would outwardly look to be so religious and pious) that everyone among you would consider his prayer insignificant as compared with their prayer, and his fast as compared with their fasts. They would recite the Qur'an but it would not go beyond their collar-bones. They would pass through (the teachings of Islam so hurriedly) just as the arrow passes through the prey. He would look at its Iron head, but would not find anything ticking) there. He would then see at the lowest end, but would not find anything sticking there. He would then see at its grip but would not find anything sticking to it. He would then see at its feathers and he would find nothing sticking to them (as the arrow would pass so quickly that nothing would stick to it) neither excrement nor blood. They would be recognised by the presence of a black man among them whose upper arms would be like a woman's breast, or like a piece of meat as it quivers, and they would come forth at the time when there is dissension among the people. Abu Sai'd said: I testify to the fact that I heard it from the Messenger of Allah ﷺ, and I testify to the fact that 'Ali b. Abu Talib fought against them and I was with him. He gave orders about that man who was sought for, and when he was brought in, and when I looked at him, he was exactly as the Messenger of Allah ﷺ had described him. (Using translation from Muslim 1064f)
بَيْنَمَا نَحْنُ عِنْدَ رَسُولِ اللَّهِ ﷺ وَهُوَ يُقْسِمُ قَسْمًا إِذَا جَاءَهُ ذُو الْخُوَيْصِرَةِ وَهُوَ رَجُلٌ مِنْ بَنِي تَمِيمٍ فَقَالَ يَا رَسُولَ اللَّهِ اعْدِلْ فَقَالَ رَسُولُ اللَّهِ ﷺ «وَيْلَكَ وَمَنْ يَعْدِلُ إِذَا لَمْ أَعْدَلْ؟ » قَالَ عُمَرُ بْنُ الْخَطَّابِ يَا رَسُولَ اللَّهِ ائْذَنْ لِي فِيهِ أَضْرِبْ عُنُقَهُ قَالَ رَسُولُ اللَّهِ ﷺ «دَعْهُ فَإِنَّ لَهُ أَصْحَابًا يَحْقِرُ أَحَدُكُمْ صَلَاتَهُ مَعَ صَلَاتِهِمْ وَصِيَامَهُ مَعَ صِيَامِهِمْ يَقْرَءُونَ الْقُرْآنَ لَا يُجَاوِزُ تَرَاقِيَهُمْ يَمْرُوقُونَ مِنَ الْإِسْلَامِ كَمَا يَمْرُقُ السَّهْمُ مِنَ الرَّمِيَّةِ يُنْظَرُ إِلَى نَصْلِهِ فَلَا يُوجَدُ فِيهِ شَيْءٌ ثُمَّ يُنْظَرُ إِلَى رِصَافِهِ فَلَا يُوجَدُ فِيهِ شَيْءٌ ثُمَّ يُنْظَرُ إِلَى نَضِيِّهِ فَلَا يُوجَدُ فِيهِ شَيْءٌ وَهُوَ الْقِدْحُ ثُمَّ يُنْظَرُ إِلَى قُذَذِهِ فَلَا يُوجَدُ فِيهِ شَيْءٌ سَبَقَ الْفَرْثَ وَالدَّمَ آيَتُهُمْ رَجُلٌ أَسْوَدُ إِحْدَى عَضُدَيْهِ مِثْلُ ثَدْيِ الْمَرْأَةِ وَمَثَلُ الْبَضْعَةِ تَدَرْدَرُ يَخْرُجُونَ عَلَى حِينَ فُرْقَةٍ مِنَ النَّاسِ» قَالَ أَبُو سَعِيدٍ فَأَشْهَدُ أَنِّي سَمِعْتُ هَذَا مِنْ رَسُولِ اللَّهِ ﷺ وَأَشْهَدُ أَنَّ عَلِيَّ بْنَ أَبِي طَالِبٍ قَاتَلَهُمْ وَأَنَا مَعَهُ فَأَمَرَ بِذَلِكَ الرَّجُلِ فَالْتُمِسَ فَوُجِدَ فَأُتِيَ بِهِ حَتَّى نَظَرْتُ إِلَيْهِ عَلَى نَعْتِ رَسُولِ اللَّهِ ﷺ الَّذِي نَعَتَ
