When Haruria (the Khawarij) set out and as he was with 'Ali b. Abu Talib (Allah be pleased with him) they said, "There is no command but that of Allah." Upon this 'Ali said: The statement is true but it is intentionally applied (to support) a wrong (cause). The Messenger of Allah ﷺ described their characteristics and I found these characteristics in them. They state the truth with their tongue, but it does not go beyond this part of their bodies (and the narrator pointed towards his throat). The most hateful among the creation of Allah is one black man among them (Khawarij). One of his hand is like the teat of a goat or the nipple of the breast. When 'Ali b. Abu Talib (Allah be pleased with him) killed them, he said: Search (for his dead body). They searched for him, but they did not find it (his dead body). Upon this he said: Go (and search for him). By Allah, neither I have spoken a lie nor has the lie been spoken to me. 'Ali said this twice and thrice. They then found him (the dead body) in a rain. They brought (his dead) body till they placed it before him (Hadrat 'Ali). 'Ubaidullah said: And, I was present at (that place) when this happened and when 'Ali said about them. A person narrated to me from Ibn Hanain that he said: I saw that black man.  

عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي رَافِعٍ مَوْلَى رَسُولِ اللَّهِ ﷺ أَنَّ الْحَرُورِيَّةَ لَمَّا خَرَجَتْ وَهُوَ مَعَ عَلِيِّ بْنِ أَبِي طَالِبٍ ؓ قَالُوا لاَ حُكْمَ إِلاَّ لِلَّهِ قَالَ عَلِيٌّ كَلِمَةُ حَقٍّ أُرِيدَ بِهَا بَاطِلٌ إِنَّ رَسُولَ اللَّهِ ﷺ وَصَفَ نَاسًا إِنِّي لأَعْرِفُ صِفَتَهُمْ فِي هَؤُلاَءِ يَقُولُونَ الْحَقَّ بِأَلْسِنَتِهِمْ لاَ يَجُوزُ هَذَا مِنْهُمْ وَأَشَارَ إِلَى حَلْقِهِ مِنْ أَبْغَضِ خَلْقِ اللَّهِ إِلَيْهِ مِنْهُمْ أَسْوَدُ إِحْدَى يَدَيْهِ طُبْىُ شَاةٍ أَوْ حَلَمَةُ ثَدْىٍ فَلَمَّا قَتَلَهُمْ عَلِيُّ بْنُ أَبِي طَالِبٍ ؓ قَالَ انْظُرُوا فَنَظَرُوا فَلَمْ يَجِدُوا شَيْئًا فَقَالَ ارْجِعُوا فَوَاللَّهِ مَا كَذَبْتُ وَلاَ كُذِبْتُ مَرَّتَيْنِ أَوْ ثَلاَثًا ثُمَّ وَجَدُوهُ فِي خَرِبَةٍ فَأَتَوْا بِهِ حَتَّى وَضَعُوهُ بَيْنَ يَدَيْهِ قَالَ عُبَيْدُ اللَّهِ وَأَنَا حَاضِرُ ذَلِكَ مِنْ أَمْرِهِمْ وَقَوْلِ عَلِيٍّ فِيهِمْ زَادَ يُونُسُ فِي رِوَايَتِهِ قَالَ بُكَيْرٌ وَحَدَّثَنِي رَجُلٌ عَنِ ابْنِ حُنَيْنٍ أَنَّهُ قَالَ رَأَيْتُ ذَلِكَ الأَسْوَدَ  

[Machine] Ubaidullah bin Abi Rafi, the servant of the Messenger of Allah ﷺ , narrated to me that when the Haruriyyah rebels appeared while he was with Ali (may Allah be pleased with him), they said, "There is no ruling except for Allah." Ali said, "This is a truthful statement, but they intend falsehood. Indeed, the Messenger of Allah ﷺ described certain people, and I know the description of those individuals. They claim the truth with their tongues, but it is not permissible for them. He pointed towards his throat, indicating the most hated creation of Allah among them, whose one hand has a black mole resembling a nipple. When Ali killed them, he said, "Look!" They looked but did not find him. Ali said, "Go back, by Allah, I have not lied nor have I been lied to twice or thrice." Then they found him in a ruin, so they brought him until they placed him before Ali. I, Ubaidullah, was present at that moment during their conversation and the words of Ali about them.  

أَنَّ عُبَيْدَ اللَّهِ بْنَ أَبِي رَافِعٍ مَوْلَى رَسُولِ اللَّهِ ﷺ حَدَّثَهُ أَنَّ الْحَرُورِيَّةَ لَمَّا خَرَجَتْ وَهُوَ مَعَ عَلِيٍّ فَقَالُوا لَا حُكْمَ إِلَّا لِلَّهِ فَقَالَ عَلِيٌّ ؓ كَلِمَةُ حَقٍّ أُرِيدَ بِهَا بَاطِلٌ إِنَّ رَسُولَ اللَّهِ ﷺ وَصَفَ أُنَاسًا إِنِّي لَأَعْرِفُ وَصْفَهُمْ فِي هَؤُلَاءِ «يَقُولُونَ الْحَقَّ بِأَلْسِنَتِهِمْ لَا يَجُوزُ هَذَا مِنْهُمْ وَأَشَارَ إِلَى حَلْقِهِ مِنْ أَبْغَضِ خَلْقِ اللَّهِ إِلَيْهِ فِيهِمْ أَسْوَدُ إِحْدَى يَدَيْهِ حَلَمَةُ ثَدْيٍ فَلَمَّا قَتَلَهُمْ عَلِيٌّ ؓ قَالَ انْظُرُوا فَنَظَرُوا فَلَمْ يَجِدُوا فَقَالَ ارْجِعُوا فَوَاللَّهِ مَا كَذَبْتُ وَلَا كُذِبْتُ مَرَّتَيْنِ أَوْ ثَلَاثًا ثُمَّ وَجَدُوهُ فِي خَرِبَةٍ فَأَتَوْا بِهِ حَتَّى وَضَعُوهُ بَيْنَ يَدَيْهِ قَالَ عُبَيْدُ اللَّهِ وَأَنَا حَاضِرٌ ذَلِكَ مِنْ أَمْرِهِمْ وَقَوْلِ عَلِيٍّ فِيهِمْ

عَلِيٌّ «كَلِمَةُ حَقٍّ أُرِيدَ بِهَا بَاطِلٌ إِنَّ رَسُولَ اللهِ ﷺ وَصَفَ نَاسًا إِنِّي لَأَعْرِفُ صِفَتَهُمْ فِي هَؤُلَاءِ الَّذِينَ يَقُولُونَ الْحَقَّ بِأَلْسِنَتِهِمْ لَا يَجُوزُ هَذَا مِنْهُمْ وَأَشَارَ إِلَى حَلْقِهِ مِنْ أَبْغَضِ خَلْقِ اللهِ إِلَيْهِ مِنْهُمْ أَسْوَدُ إِحْدَى يَدَيْهِ طُبْيُ شَاةٍ أَوْ حَلَمَةُ ثَدْيٍ فَلَمَّا قَاتَلَهُمْ عَلِيٌّ» قَالَ انْظُرُوا فَنَظَرُوا فَلَمْ يَجِدُوا شَيْئًا فَقَالَ «ارْجِعُوا وَاللهِ مَا كَذَبْتُ وَلَا كُذِبْتُ مَرَّتَيْنِ أَوْ ثَلَاثًا ثُمَّ وَجَدُوهُ فِي خَرِبَةٍ فَأَتَوْا بِهِ حَتَّى وَضَعُوهُ بَيْنَ يَدَيْهِ» قَالَ عُبَيْدُ اللهِ «أَنَا حَاضِرٌ ذَلِكَ مِنْ أَمْرِهِمْ وَقَوْلُ عَلِيٍّ فِيهِمْ»  

"عن عبيد الله بن أبى رافع: أن الحرورية لما خرجت وهم مع على بن أبى طالب قالوا: لا حكم إلا لله، قال على: كلمة حق أريد بها باطل، إن رسول الله ﷺ وصف ناسا إنى لأعرف صفتهم في هؤلاء، يقولون الحق بألسنتهم لا يجوز هذا منهم - وأشار إلى حلقه - من أبغض خلق الله إليه منهم - أسود، إحدى يديه طُبْىُ شاة أو حلمة ثدى، فلما قتلهم على بن أبى طالب قال: انظروا، فنظروا فلم يجدوا شيئًا، فقال: ارجعوا فوالله ما كُذِبْتُ ولا كذَبْتُ - مرتين أو ثلاثًا - ثم وجدوه في خربة، فأتوا به حتى وضعوه بين يديه".
