[Machine] What prevents you from this matter, while you are the companion of the Messenger of Allah ﷺ and the son of the Commander of the Faithful? He said, "What prevents me from it is that Allah ﷻ has forbidden me from shedding the blood of my Muslim brother." He said, "Indeed, Allah ﷻ says: 'And fight them until there is no fitnah [disbelief and polytheism] and [until] the religion, all of it, is for Allah.'" Ibn Umar said, "We have certainly fought them until there was no fitnah and the religion, all of it, was for Allah, while you [O Ubaydullah] want me to fight until there is fitnah and the religion is for someone other than Allah."
مَا يَمْنَعُكُ مِنْ هَذَا الْأَمْرِ وَأَنْتَ صَاحِبُ رَسُولِ اللهِ ﷺ وَابْنُ أَمِيرِ الْمُؤْمِنِينَ؟ فَقَالَ «مَا يَمْنَعُنِي مِنْهِ أَنَّ اللهَ ﷻ حَرَّمَ عَلَيَّ دَمَ أَخِي الْمُسْلِمِ» قَالَ فَإِنَّ اللهَ ﷻ يَقُولُ {وَقَاتِلُوهُمْ حَتَّى لَا تَكُونَ فِتْنَةٌ وَيَكُونَ الدِّينُ كُلُّهُ لِلَّهِ} قَالَ فَقَالَ ابْنُ عُمَرَ «فَقَدْ قَاتَلْنَاهُمْ حَتَّى لَمْ تَكُنْ فِتْنَةٌ وَكَانَ الدِّينُ كُلُّهُ لِلَّهِ وَأَنْتُمْ تُرِيدُونَ أَنْ أُقَاتِلَ حَتَّى تَكُونَ فِتْنَةٌ وَيَكُونَ الدِّينُ لِغَيْرِ اللهِ»
