The Prophet ﷺ said: Striving in the path of Allah (jihad) is incumbent on you along with every ruler, whether he is pious or impious; the prayer is obligatory on you behind every believer, pious or impious, even if he commits grave sins; the (funeral) prayer is incumbent upon every Muslim, pious and impious, even if he commits major sins. (Using translation from Abū Dāʾūd 2533)   

قَالَ رَسُولُ اللهِ ﷺ الْجِهَادُ وَاجِبٌ عَلَيْكُمْ مَعَ كُلِّ أَمِيرٍ بَرًّا كَانَ أَوْ فَاجِرًا وَالصَّلَاةُ وَاجِبَةٌ عَلَيكُمْ خَلْفَ كُلِّ مُسْلِمٍ بَرًّا كَانَ أَوْ فَاجِرًا وَإِنْ عَمِلَ الْكَبَائِرَ وَالصَّلَاةُ وَاجِبَةٌ عَلَى كُلِّ مُسْلِمٍ بَرًّا كَانَ أَوْ فَاجِرًا وَإِنْ عَمِلَ الْكَبَائِرَ  

[Machine] Ibn Umar withdrew from Mina during the battles between Ibn Zubayr and Al-Hajjaj in Mina, and he prayed with Al-Hajjaj.  

أَنَّ ابْنَ عُمَرَ اعْتَزَلَ بِمِنًى فِي قِتَالِ ابْنِ الزُّبَيْرِ وَالْحَجَّاجُ بِمِنًى فَصَلَّى مَعَ الْحَجَّاجِ  

[Machine] "O brother of the people of Sham, I am not one who praises them nor do I obey a creation in disobedience to the Creator." He said, "What do you say about the people of Sham?" He said, "I am not one who praises them." I said, "So what do you say about the people of Makkah?" He said, "I am not one who excuses them. They fight over the worldly life and compete in entering the Fire, like flies compete over a broth." I said, "So what is your opinion about this allegiance that Marwan has imposed upon us?" He said, "Ibn Umar said: When we pledged allegiance to the Messenger of Allah ﷺ for hearing and obeying, he would teach us to the best of our ability."  

يَا أَخَا أَهْلِ الشَّامِ مَا أَنَا لَهُمْ بِحَامِدٍ وَلَا نُطِيعُ مَخْلُوقًا فِي مَعْصِيَةِ الْخَالِقِ قَالَ قُلْتُ مَا تَقُولُ فِي أَهْلِ الشَّامِ؟ قَالَ مَا أَنَا لَهُمْ بِحَامِدٍ قُلْتُ فَمَا تَقُولُ فِي أَهْلِ مَكَّةَ؟ قَالَ مَا أَنَا لَهُمْ بِعَاذِرٍ يَقْتَتِلُونَ عَلَى الدُّنْيَا يَتَهَافَتُونَ فِي النَّارِ تَهَافُتَ الذُّبَابُ فِي الْمَرَقِ قُلْتُ فَمَا قَوْلُكَ فِي هَذِهِ الْبَيْعَةِ الَّتِي أَخَذَ عَلَيْنَا مَرْوَانُ؟ قَالَ قَالَ ابْنُ عُمَرَ كُنَّا إِذَا بَايَعْنَا رَسُولَ اللهِ ﷺ عَلَى السَّمْعِ وَالطَّاعَةِ يُلَقِّنُنَا فِيمَا اسْتَطَعْتُمْ  

[Machine] No, by Allah, they did not exceed the prayer of the imams.  

لَا وَاللهِ مَا كَانَا يَزِيدَانِ عَلَى صَلَاةِ الْأَئِمَّةِ  

[Machine] I met ten companions of the Prophet ﷺ, all of them used to pray behind the leaders of the prayer.  

أَدْرَكْتُ عَشَرَةً مِنْ أَصْحَابِ النَّبِيِّ ﷺ كُلُّهُمْ يُصَلِّي خَلْفَ أَئِمَّةِ الْجَوْرِ  

[Machine] I said no to the idea of killing your Muslim brother and taking his money.  

حِيَّ عَلَى قَتْلِ أَخِيكَ الْمُسْلِمِ وَأَخْذِ مَالِهِ قُلْتُ لَا
