Al-Qurtubi reported: Al-Kalbi, may Allah have mercy on him, said, “It was the habit of the Arabs that if a man among them desired anything, he would worship it besides Allah. If he saw something better, he would leave what he first worshipped and worship what is better. This is the meaning of the verse: Have you seen one who takes his desires as his god?” (25:43)
