“And Ruh bin Zinba’ was traveling between Makkah and Madinah on a very hot day. A herder living on a mountain approached him, and he said to him: “O herder, come eat with me.” The herder said: “I’m fasting.” Ruh said: “You’re fasting in this heat?” The herder replied: “Should I let my days pass by in vain?” So, Ruh said: “You have used your days wisely, O herder, while Ruh bin Zinba’ has wasted his.”
