Salim narrated on the authority of his father (Ibn 'Umar) that the Apostle of Allah (may peace be upon him) said: Envy is not justified but in case of two persons only: one who, having been given (knowledge of) the Qur'an by Allah, recites it during the night and day (and also acts upon it) and a man who, having been given wealth by God, spends it during the night and the day (for the welfare of others. seeking the pleasure of the Lord).
