Permissible envy in two cases

عَنْ عَبْدِ اللَّهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم: لاَ حَسَدَ إِلاَّ فِي اثْنَتَيْنِ، رَجُلٌ آتَاهُ اللَّهُ مَالاً فَسَلَّطَهُ عَلَى هَلَكَتِهِ فِي الْحَقِّ، وَآخَرُ آتَاهُ اللَّهُ حِكْمَةً فَهْوَ يَقْضِي بِهَا وَيُعَلِّمُهَا ‏”‏‏.‏

Hazrat ‘Abdullah^ra [Ibn Mas‘ud] narrated:

“Allah’s Messenger^sa said, “Envy is not appropriate except in two cases: a man whom Allah has given wealth and has enabled him to spend it in what is right and another whom Allah has given wisdom, so he judges by it and teaches it.’”
