Sahih al-Bukhari, Hadith 1409 ⓘ
Narrated Ibn Mas`ud: I heard the Prophet saying, "There is no envy except in two: a person whom Allah has given wealth and he spends it in the right way, and a person whom Allah has given wisdom (i.e. religious knowledge) and he gives his decisions accordingly and teaches it to the others."
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى، عَنْ إِسْمَاعِيلَ، قَالَ حَدَّثَنِي قَيْسٌ، عَنِ ابْنِ مَسْعُودٍ ـ رضى الله عنه ـ قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " لاَ حَسَدَ إِلاَّ فِي اثْنَتَيْنِ رَجُلٌ آتَاهُ اللَّهُ مَالاً فَسَلَّطَهُ عَلَى هَلَكَتِهِ فِي الْحَقِّ، وَرَجُلٌ آتَاهُ اللَّهُ حِكْمَةً فَهْوَ يَقْضِي بِهَا وَيُعَلِّمُهَا " .
