I swear by Allah, I heard the Messenger of Allah ﷺ say: The happy man is he who avoids dissensions: happy is the man who avoids dissensions; happy is the man who avoids dissensions: but how fine is the man who is afflicted and shows endurance. (Using translation from Abū Dāʾūd 4263)   

السيوطي:٥٥٨٩a –

"إنَّ السَّعِيدَ لَمَنْ جُنِّبَ الْفِتَنَ، إِنَّ السَّعيدَ لَمَنْ جُنِّبَ الْفتَنَ، إِنَّ السَّعِيدَ لَمَنْ جُنِّبَ الْفِتَنَ، وَلَمَنْ ابْتُلِى فَصَبَرَ، فواهًا ثُمَّ وَاهًا".

أبو داود:٤٢٦٣ – حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْحَسَنِ الْمِصِّيصِيُّ حَدَّثَنَا حَجَّاجٌ يَعْنِي ابْنَ مُحَمَّدٍ حَدَّثَنَا اللَّيْثُ بْنُ سَعْدٍ قَالَ حَدَّثَنِي مُعَاوِيَةُ بْنُ صَالِحٍ أَنَّ عَبْدَ الرَّحْمَنِ بْنَ جُبَيْرٍ حَدَّثَهُ عَنْ أَبِيهِ عَنِ الْمِقْدَادِ بْنِ الأَسْوَدِ قَالَ ايْمُ اللَّهِ لَقَدْ

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ السَّعِيدَ لَمَنْ جُنِّبَ الْفِتَنَ إِنَّ السَّعِيدَ لَمَنْ جُنِّبَ الْفِتَنَ إِنَّ السَّعِيدَ لَمَنْ جُنِّبَ الْفِتَنَ وَلَمَنِ ابْتُلِيَ فَصَبَرَ فَوَاهًا
