Worshiping during the period of widespread turmoil is like emigration towards me.  

مسلم:٢٩٤٨a – حَدَّثَنَا يَحْيَى بْنُ يَحْيَى أَخْبَرَنَا حَمَّادُ بْنُ زَيْدٍ عَنْ مُعَلَّى بْنِ زِيَادٍ عَنْ مُعَاوِيَةَ بْنِ قُرَّةَ عَنْ مَعْقِلِ بْنِ يَسَارٍ

أَنَّ رَسُولَ اللَّهِ ﷺ ح وَحَدَّثَنَاهُ قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا حَمَّادٌ عَنِ الْمُعَلَّى بْنِ زِيَادٍ رَدَّهُ إِلَى مُعَاوِيَةَ بْنِ قُرَّةَ رَدَّهُ إِلَى مَعْقِلِ بْنِ يَسَارٍ رَدَّهُ إِلَى النَّبِيِّ ﷺ قَالَ الْعِبَادَةُ فِي الْهَرْجِ كَهِجْرَةٍ إِلَىَّ

"Worship during Al-Harj is like Hijrah to me."  

الترمذي:٢٢٠١ – حَدَّثَنَا قُتَيْبَةُ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ

عَنِ الْمُعَلَّى بْنِ زِيَادٍ رَدَّهُ إِلَى مُعَاوِيَةَ بْنِ قُرَّةَ رَدَّهُ إِلَى مَعْقِلِ بْنِ يَسَارٍ رَدَّهُ إِلَى النَّبِيِّ ﷺ قَالَ الْعِبَادَةُ فِي الْهَرْجِ كَالْهِجْرَةِ إِلَىَّ  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ صَحِيحٌ غَرِيبٌ إِنَّمَا نَعْرِفُهُ مِنْ حَدِيثِ حَمَّادِ بْنِ زَيْدٍ عَنِ الْمُعَلَّى
