Nahj al-Balāgha

۳۸۵. وَقَالَ (عليه ‏السلام): مِنْ هَوَانِ الدُّنْيَا عَلَى اللهِ أَنَّهُ لَا يُعْصَى إِلَّا فِيهَا، وَلَا يُنَالُ مَا عِنْدَهُ إِلَّا بِتَرْكِهَا.

385. Amīr al-mu’minīn, peace be upon him, said: It is (the proof of the) humbleness of the world before Allāh that He is disobeyed only herein and His favours cannot be achieved except by abandoning it.
