Enter it. Some people wanted to enter it, but others said: This is what we wanted to flee from. That was mentioned to the Messenger of Allah ﷺ and he said to those who had wanted to enter it: “If you had entered it you would have remained in it until the Day of Resurrection.” He said some kind words to the others, then he said: ʿThere is no obedience in that which involves disobedience towards Allah; obedience is only with regard to that which is right and proper.ʿ (Using translation from Aḥmad 724)   

أَنَّ رَسُولَ اللهِ ﷺ بَعَثَ جَيْشًا وَأَمَّرَ عَلَيْهِمْ رَجُلًا فَأَوْقَدَ نَارًا فَقَالَ ادْخُلُوهَا فَأَرَادَ نَاسٌ أَنْ يَدْخُلُوهَا وَقَالَ الْآخَرُونَ إِنَّمَا فَرَرْنَا مِنْهَا فَذَكَرَ ذَلِكَ لِرَسُولِ اللهِ ﷺ فَقَالَ لِلَّذِينَ أَرَادُوا أَنْ يَدْخُلُوهَا «لَوْ دَخَلْتُمُوهَا لَمْ تَزَالُوا فِيهَا إِلَى يَوْمِ الْقِيَامَةِ» وَقَالَ لِلْآخَرِينَ خَيْرًا وَقَالَ ابْنُ الْمُثَنَّى قَوْلًا حَسَنًا  

It is obligatory upon a Muslim that he should listen (to the ruler appointed over him) and obey him whether he likes it or not, except that he is ordered to do a sinful thing. If he is ordered to do a sinful act, a Muslim should neither listen to him nor should he obey his orders. (Using translation from Muslim 1839a)  

قَالَ رَسُولُ اللهِ ﷺ «عَلَى الْمَرْءِ الْمُسْلِمِ السَّمْعُ وَالطَّاعَةُ فِيمَا أَحَبَّ وَكَرِهَ إِلَّا أَنْ يُؤْمَرَ بِمَعْصِيَةٍ فَإِذَا أُمِرَ بِمَعْصِيَةٍ فَلَا سَمْعَ وَلَا طَاعَةَ»
