Umar II on Jihad: Our sins more harmful than plots of enemies

Maslamah ibn Abi Bakr reported: Umar ibn Abdul Aziz, may Allah have mercy on him, took a pledge from some of his military deputies, saying, “You must fear Allah in every situation you find yourselves. Verily, the fear of Allah is greater for preparation, a better plan, and a stronger force. There is nothing of the hostility of your enemies that deserves more caution than your own selves. and those with you who are sinfully disobedient to Allah. For I fear the sins of the people more than the plots of their enemies. Verily, we were only transgressed by our enemy and given divine support over them due to their sinful disobedience. Were it not for that, we would have no power over them.”

عَنْ مَسْلَمَةَ بْنِ أَبِي بَكْرٍ أَنَّ عُمَرَ بْنَ عَبْدِ الْعَزِيزِ رحمه الله عَهِدَ إِلَى بَعْضِ عُمَّالِهِ عَلَيْكَ بِتَقْوَى اللَّهِ فِي كُلِّ حَالٍ يَنْزِلُ بِكَ فَإِنَّ تَقْوَى اللَّهِ أَفْضَلُ الْعُدَّةِ وَأَبْلَغُ الْمَكِيدَةِ وَأَقْوَى الْقُوَّةِ وَلا تَكُنْ فِي شَيْءٍ مِنْ عَدَاوَةِ عَدُوِّكَ أَشَدَّ احْتِرَاسًا لِنَفْسِكَ وَمَنْ مَعَكَ مِنْ مَعَاصِي اللَّهِ فَإِنَّ الذُّنُوبَ أَخْوَفُ عِنْدِي عَلَى النَّاسِ مِنْ مَكِيدَةِ عَدُوِّهِمْ وَإِنَّمَا نُعَادِي عَدُوَّنَا وَنَسْتَنْصِرُ عَلَيْهِمْ بِمَعْصِيَتِهِمْ وَلَوْلا ذَلِكَ لَمْ تَكُنْ لَنَا قُوَّةٌ بِهِمْ
