يَا جَرِيرُ إِنَّ بِكَ عَلَىَّ كَرَامَةً، وَإِنِّي مُخْبِرُكَ خَبَرًا، إِنَّكُمْ مَعْشَرَ الْعَرَبِ لَنْ تَزَالُوا بِخَيْرٍ مَا كُنْتُمْ إِذَا هَلَكَ أَمِيرٌ تَأَمَّرْتُمْ فِي آخَرَ، فَإِذَا كَانَتْ بِالسَّيْفِ كَانُوا مُلُوكًا يَغْضَبُونَ غَضَبَ الْمُلُوكِ وَيَرْضَوْنَ رِضَا الْمُلُوكِ

“O Jarir! You have done a favor to me and I am going to tell you something, i.e. you, the nation of ‘Arabs, will remain prosperous as long as you choose and appoint another chief whenever a former one is dead. But if authority is obtained by the power of the sword, then the rulers will become kings who will get angry, as kings get angry, and will be delighted as kings get delighted.”(Sahih Bukhari V5,# 645)
