[Machine] Two men came to him during the turmoil of Ibn Zubayr and said to him, "People have done what you see, and you are Ibn Umar bin Khattab, the companion of the Messenger of Allah ﷺ, so what prevents you from going out?" He said, "What prevents me is that Allah has forbidden me to shed the blood of my Muslim brother." They said, "Didn't Allah say, 'And fight them until there is no more Fitnah (disbelief, polytheism: i.e. worshipping others besides Allah) and the religion (worship) will all be for Allah Alone? [Surah Al-Anfal, 39]'." He said, "We have already fought until there is no more Fitnah and the religion is for Allah, but you want us to fight until there is Fitnah and the religion is for other than Allah?"  

أَنَّهُ أَتَاهُ رَجُلَانِ فِي فِتْنَةِ ابْنِ الزُّبَيْرِ فَقَالَا إِنَّ النَّاسَ قَدْ صَنَعُوا مَا تَرَى وَأَنْتَ ابْنُ عُمَرَ بْنِ الْخَطَّابِ صَاحِبُ رَسُولِ اللهِ ﷺ فَمَا يَمْنَعُكَ أَنْ تَخْرُجَ؟ قَالَ يَمْنَعُنِي أَنَّ اللهَ حَرَّمَ عَلَيَّ دَمَ أَخِي الْمُسْلِمِ قَالَ أَوَ لَمْ يَقُلِ اللهُ ﷻ {وَقَاتِلُوهُمْ حَتَّى لَا تَكُونَ فِتْنَةٌ وَيَكُونَ الدِّينُ كُلُّهُ لِلَّهِ} [الأنفال 39]؟ قَالَ فَقَدْ قَاتَلْنَا حَتَّى لَمْ تَكُنْ فِتْنَةٌ وَكَانَ الدِّينُ لِلَّهِ وَأَنْتُمْ تُرِيدُونَ أَنْ نُقَاتِلَ حَتَّى تَكُونَ فِتْنَةٌ وَيَكُونَ الدِّينُ لِغَيْرِ اللهِ
