Ibn ‘Asakir reported: ‘Amr ibn al-‘As, may Allah be pleased with him, said to his son, “My son, memorize what I instruct you: a just leader is better than abundant rain, a predatory lion is better than an oppressive leader, and an oppressive and tyrannical leader is better than an everlasting tribulation.”

Ibn Taymiyyah said, “It is said that sixty years of a tyrannical leader is more proper than a single night without an authority, and experience has proven this true.”

عن ابن عساكر قَالَ عَمْرُو بْنُ الْعَاصِ رضي الله عنه لِابْنِهِ يَا بُنَيّ احْفَظْ عَنِّي مَا أُوصِيكَ بِهِ إمَامٌ عَدْلٌ خَيْرٌ مِنْ مَطَرٍ وَبْلٍ وَأَسَدٌ حَطُومٌ خَيْرٌ مِنْ إمَامٍ ظَلُومٍ وَإِمَامٌ ظَلُومٌ غَشُومٌ خَيْرٌ مِنْ فِتْنَةٍ تَدُومُ

قال ابن تيمية وَيُقَالُ سِتُّونَ سَنَةً مِنْ إمَامٍ جَائِرٍ أَصْلَحُ مِنْ لَيْلَةٍ وَاحِدَةٍ بِلَا سُلْطَانٍ وَالتَّجْرِبَةُ تُبَيِّنُ ذَلِكَ
