Divine punishment through worldly indulgence
Nahj al-Balāgha|Volume 1|Book 3|Chapter 260
٢٦٠. وَقَالَ (عليه السلام): كَمْ مِنْ مُسْتَدْرَجٍ بِالْإِحْسَانِ إِلَيْهِ، وَمَغْرُورٍ بِالسَّتْرِ عَلَيْهِ، وَمَفْتُونٍ بِحُسْنِ الْقَوْلِ فِيهِ، وَمَا ابْتَلَى اللهُ سُبْحَانَهُ أَحَداً بِمِثْلِ الْإِمْلَاءِ لَهُ.
260. Amīr al-mu’minīn, peace be upon him, said: There is many a man being gradually brought towards punishment by good treatment with him; many a man who remains in deceit because his evils are covered; and many a man who is in illusion because of good talk about him, while there is no greater ordeal by Allāh, the Glorified, than the giving of time.
