"Two wolves free among sheep are no more destructive to them than a man's desire for wealth and honor is to his religion." (Using translation from Tirmidhī 2376)  

قَالَ رَسُولُ اللَّهِ ﷺ «مَا ذِئْبَانِ جَائِعَانِ أُرْسِلَا فِي غَنَمٍ بِأَفْسَدَ لَهَا مِنْ حِرْصِ الْمَرْءِ عَلَى الْمَالِ وَالشَّرَفِ لِدِينِهِ»
