Riyad as-Salihin

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].
