In the near future there will be Amirs and you will like their good deeds and dislike their bad deeds. One who sees through their bad deeds (and tries to prevent their repetition by his band or through his speech), is absolved from blame, but one who hates their bad deeds (in the heart of his heart, being unable to prevent their recurrence by his hand or his tongue), is (also) fafe ( so far as God's wrath is concerned). But one who approves of their bad deeds and imitates them is spiritually ruined. People asked (the Holy Prophet): Shouldn't we fight against them? He replied: No, as long as they say their prayers.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ سَتَكُونُ أُمَرَاءُ فَتَعْرِفُونَ وَتُنْكِرُونَ فَمَنْ عَرَفَ بَرِئَ وَمَنْ أَنْكَرَ سَلِمَ وَلَكِنْ مَنْ رَضِيَ وَتَابَعَ قَالُوا أَفَلاَ نُقَاتِلُهُمْ قَالَ لاَ مَا صَلَّوْا  

He who disapproves is guiltless, and he who disapproves is safe. Qatadah said : it means one who feels its disapproval in his heart, and one who expresses disapproval in his heart.  

عَنِ النَّبِيِّ ﷺ بِمَعْنَاهُ قَالَ فَمَنْ كَرِهَ فَقَدْ بَرِئَ وَمَنْ أَنْكَرَ فَقَدْ سَلِمَ قَالَ قَتَادَةُ يَعْنِي مَنْ أَنْكَرَ بِقَلْبِهِ وَمَنْ كَرِهَ بِقَلْبِهِ  

"Indeed there shall come upon you A'immah whom you like (what they do) and some (of what they do) you dislike. So whoever rejects, then he is innocent, and whoever loathes, then he is safe. But whoever is pleased and follows." It was said: "O Messenger of Allah! Shall we fight them?" He said: "No, as long as they offer Salat."  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّهُ سَيَكُونُ عَلَيْكُمْ أَئِمَّةٌ تَعْرِفُونَ وَتُنْكِرُونَ فَمَنْ أَنْكَرَ فَقَدْ بَرِئَ وَمَنْ كَرِهَ فَقَدْ سَلِمَ وَلَكِنْ مَنْ رَضِيَ وَتَابَعَ فَقِيلَ يَا رَسُولَ اللَّهِ أَفَلاَ نُقَاتِلُهُمْ قَالَ لاَ مَا صَلَّوْا

But one who approves of their bad deeds and imitates them is spiritually ruined. People asked (the Holy Prophet): Shouldn't we fight against them? He replied: No, as long as they say their prayers. (Using translation from Muslim 1854a)   

قَالَ رَسُولُ اللهِ ﷺ إِنَّهُ سَتَكُونُ أُمَرَاءُ تَعْرِفُونَ وَتُنْكِرُونَ فَمَنْ أَنْكَرَ فَقَدْ بَرِئَ وَمَنْ كَرِهَ فَقَدْ سَلِمَ وَلَكِنْ مَنْ رَضِيَ وَتَابَعَ قَالُوا يَا رَسُولَ اللهِ أَفَلَا نُقَاتِلُهُمْ؟ قَالَ لَا مَا صَلَّوْا لَكُمُ الْخَمْسَ  

"Indeed there shall come upon you A'immah whom you like (what they do) and some (of what they do) you dislike. So whoever rejects, then he is innocent, and whoever loathes, then he is safe. But whoever is pleased and follows." It was said: "O Messenger of Allah! Shall we fight them?" He said: "No, as long as they offer Salat." (Using translation from Tirmidhī 2265)   

عَنِ النَّبِيِّ ﷺ قَالَ سَيَكُونُ أُمَرَاءُ تَعْرِفُونَ وَتُنْكِرُونَ فَمَنْ أَنْكَرَ فَقَدْ بَرِئَ وَمَنْ كَرِهَ فَقَدْ سَلِمَ وَلَكِنْ مَنْ رَغِبَ وَتَابَعَ قَالُوا يَا رَسُولَ اللهِ أَلَا نُقَاتِلُهُمْ؟قَالَ لَا مَا صَلَّوْا الصَّلَاةَ  

[Machine] Narrated Umm Salamah, the wife of the Prophet ﷺ, she said: The Messenger of Allah ﷺ said, "There will be leaders after me whom you will recognize and reject. Whoever denies them, Sulaiman (one of the narrators) said Hisham (another narrator) said in his heart, he will be free (from blame). And whoever dislikes them, he will be safe (from harm). However, whoever accepts and follows them, it was said, 'O Messenger of Allah, should we not fight against them?' He said, 'No, as long as they establish the prayer.'"  

عَنْ أُمِّ سَلَمَةَ زَوْجِ النَّبِيِّ ﷺ قَالَتْ قَالَ رَسُولُ اللهِ ﷺ سَيَكُونُ عَلَيْكُمْ أَئِمَّةٌ تَعْرِفُونَ مِنْهُمْ وَتُنْكِرُونَ فَمَنْ أَنْكَرَ قَالَ سُلَيْمَانُ قَالَ هِشَامٌ بِقَلْبِهِ فَقَدْ بَرِئَ وَمَنْ كَرِهَ فَقَدْ سَلِمَ لَكِنْ مَنْ رَضِيَ وَتَابَعَ فَقِيلَ يَا رَسُولَ اللهِ أَوَلَا نُقَاتِلُهُمْ؟ فَقَالَ لَا مَا صَلَّوْا  

"ستَكُونُ أُمراءُ، فَتعْرِفُون، وتُنْكِرونَ، فَمنْ عَرَفَ بَرِئَ، ومن أَنْكَر سلِم، ولكن منْ رَضِىَ وتَابَعَ، قَالُوا: أَفَلَا نُقَاتِلُهُم؟ قَال: لَا، ما صَلُّوا".  

"إِنَّهَ سَيَكُونُ عَلَيْكُمِ أَئِمَّةٌ تعرفُونَ وَتُذْكِرُونَ فمنْ أنكر فَقَد برئَ وَمَنْ كَرهَ فقدْ سَلِمَ ولَكِنْ مَنْ رَضى وتابَعَ، قيَل يا رسولَ اللَّه: أفَلا نُقَاتِلُهُمَ، قال لا مَا صَلَّوا ".  

"عن أم سلمة قالت: قال رسول الله ﷺ يقوم عليكم أئِمَّةٌ تعرفون وتنكرون، فمن أنكر فقد نجا، ومن كره فقد سلم، ولكن من رضي وبايع قيل يا رسول الله: أفلا نقتلهم أو نقاتلهم؟ قال: أما ما صلوا الصلاة فلا".
