"Indeed there is a fitnah for every Ummah, and the Fitnah for my Ummah is wealth." (Using translation from Tirmidhī 2336)   

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ لكُلِّ أُمَّةٍ فِتْنَةً وَإِنَّ فِتْنَةَ أُمَّتِي الْمَالُ  

“I asked the Prophet ﷺ: ‘O Messenger of Allah, is it tribalism if a man loves his people?’ He said: ‘No, rather tribalism is when a man helps his people to do wrong.’” (Using translation from Ibn Mājah 3949)  

سَمِعْتُ أَبِي يَقُولُ سَأَلْتُ رَسُولَ اللهِ ﷺ فَقُلْتُ يَا رَسُولَ اللهِ أَمِنَ الْعَصَبِيَّةِ أَنْ يُحِبَّ الرَّجُلُ قَوْمَهُ؟ قَالَ لَا وَلَكِنْ مِنَ الْعَصَبِيَّةِ أَنْ يُعِينَ الرَّجُلُ قَوْمَهُ عَلَى الظُّلْمِ
