[Machine] I went out with Abu Umamah al-Bahili to the mosque of Damascus. When we were at the gate, we saw some heads of the Khawarij. When he looked at them, he cried and said, "What did Satan do three times? Dogs of the Fire." He repeated this three times, and then he said, "The worst of killers are those who kill under the shade of the sky. Whoever they kill, he is the best of victims under the shade of the sky." I said, "O Abu Umamah, are you saying this or is it something you heard from the Messenger of Allah?" He said, "If I did, then I would be audacious. Do you recite the verses in the beginning of Surah Al-Imran (As for those in whose hearts is deviation, they will follow that of it which is similar)?" These verses were revealed regarding those people, until you recite the verse that is in the middle of Surah Al-Imran (On the Day when faces will turn white and faces will turn black). These verses were revealed regarding those people. I said, "What makes you cry, O Abu Umamah?" He said, "They were believers, or he said Muslims."  

خَرَجْتُ مَعَ أَبِي أُمَامَةَ الْبَاهِلِيِّ إِلَى مَسْجِدِ دِمَشْقَ فَلَمَّا كَانَ عِنْدَ الْبَابِ فَإِذَا رُءُوسٌ مِنْ رُءُوسِ الْخَوَارِجِ فَلَمَّا نَظَرَ إِلَيْهَا بَكَى فَقَالَ «مَاذَا صَنَعَ الشَّيْطَانُ ثَلَاثًا كِلَابُ النَّارِ» ثَلَاثًا ثُمَّ قَالَ «شَرُّ قَتْلَى تَحْتَ ظِلِّ السَّمَاءِ ثَلَاثًا مَنْ قَتَلُوهُ كَانَ خَيْرَ قَتِيلٍ تَحْتَ ظِلِّ السَّمَاءِ» قُلْتُ يَا أَبَا أُمَامَةَ أَنْتَ تَقُولُهُ أَوْ شَيْءٌ سَمِعْتَهُ مِنْ رَسُولِ اللهِ ﷺ؟ قَالَ «إِنِّي إِذًا لَجَرِيءٌ هَلْ تَقْرَأُ الْآيَاتِ الَّتِي فِي أَوَّلِ آلِ عِمْرَانَ» {فَأَمَّا الَّذِينَ فِي قُلُوبِهِمْ زَيْغٌ فَيَتَّبِعُونَ مَا تَشَابَهَ مِنْهُ} فِي هَؤُلَاءِ أُنْزِلَتْ حَتَّى تَقْرَأَ الْآيَةَ الَّتِي فِي وَسَطِ آلِ عِمْرَانَ {يَوْمَ تَبْيَضُّ وُجُوهٌ وَتَسْوَدُّ وُجُوهٌ} فِي هَؤُلَاءِ أُنْزِلَتْ قُلْتُ مَا يُبْكِيكَ يَا أَبَا أُمَامَةَ؟ قَالَ «إِنَّهُمْ كَانُوا مُؤْمِنِينَ» أَوْ قَالَ مُسْلِمِينَ
