It is reported that Muhammad b. Sîrîn – Allâh have mercy on him – said, “I have never envied anyone over anything: if a person is going to be in the Fire, how could I envy him over some worldly matter when he is destined for the Fire?! And if he is going to Paradise, how could I be envious of a man of Paradise with whom Allâh tabâraka wa ta’âlâ is pleased?!” Muslim said, “We have never heard anything better than this from the words of Ibn Sîrîn.”
