It is reported that Muḥammad b. Sīrīn – Allāh 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 Allāh tabāraka wa ta’ālā is pleased?!” Muslim said, “We have never heard anything better than this from the words of Ibn Sīrīn.”
