[Machine] "He who worships without knowledge, his actions will cause more harm than benefit. Whoever judges his words based on his actions, his words will be minimal except for what he means. And whoever uses his religion for disputes, his movements will be plentiful."  

الدارمي:٣١٣أَخْبَرَنَا مَرْوَانُ بْنُ مُحَمَّدٍ حَدَّثَنَا سَعِيدُ بْنُ عَبْدِ الْعَزِيزِ قَالَ «كَتَبَ عُمَرُ بْنُ عَبْدِ الْعَزِيزِ إِلَى أَهْلِ الْمَدِينَةِ

أنَّهُ مَنْ تَعَبَّدَ بِغَيْرِ عِلْمٍ كَانَ مَا يُفْسِدُ أَكْثَرَ مِمَّا يُصْلِحُ وَمَنْ عَدَّ كَلَامَهُ مِنْ عَمَلِهِ قَلَّ كَلَامُهُ إِلَّا فِيمَا يَعْنِيهِ وَمَنْ جَعَلَ دِينَهُ غَرَضًا لِلْخُصُومَاتِ كَثُرَ تَنَقُّلُهُ»
