Hadith 20:543
Ibn Mas'ud (May Allah be pleased with him) reported:
The Prophet (ﷺ) said, "Envy is permitted only in two cases: A man whom Allah gives wealth, and he disposes of it rightfully, and a man to whom Allah gives knowledge which he applies and teaches it." [Al- Bukhari and Muslim] .
وعن ابن مسعود رضي الله عنه عن النبي صلى الله عليه وسلم قال: "لا حسد إلا فى اثنتين: رجل آتاه الله مالاً، فسلطه على هلكته فى الحق، ورجل آتاه الله حكمة، فهو يقضي بها ويعلمها" ((متفق عليه)).
