Muhammad Ibn Sireen 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?”

[Abu Bakr Al-Daynooree, Al-Mujâlasah wa Jawaahir Al-‘Ilm, 2931]
