Riyad as-Salihin 571
Ibn 'Umar (May Allah be pleased with him) reported:
Messenger of Allah (ﷺ) said: "Envy is justified in regard to two types of persons only: a man whom Allah has given knowledge of the Qur'an, and so he recites it during the night and during the day; and a man whom Allah has given wealth and so he spends from it during the night and during the day." [Al-Bukhari and Muslim] .
وعن ابن عمر رضي الله عنهما‏:‏ عن النبي صلى الله عليه وسلم  قال ‏:‏‏"‏ لا حسد إلى فى اثنتين‏:‏ رجل آتاه الله القرآن، فهو يقوم به آناء الليل وآناء النهار، ورجل آتاه الله مالاً فهو ينفقه آناء الليل وآناء النهار” ‏(‏‏(‏متفق عليه‏)‏‏)‏

“الآناء”:الساعات .‏
