It is narrated from Imam Hasan al-Basri, may Allah have mercy on him, that he said: When a people consult each other in a matter, they are surely guided to the best course of action. Then he recited this verse: «﴿وَأَمْرُهُمْ شُورَىٰ بَيْنَهُمْ﴾» [الشورى: 38] "And their affairs are (decided) by mutual consultation among them."
