Mishkat al-Masabih 2114

Abū Mūsa al-Ash'ari reported God’s messenger as saying, “A be­liever who recites the Qur’ān is like a citron whose fragrance is sweet and whose taste is sweet, a believer who does not recite the Qur’ān is like a date which has no fragrance but has a sweet state, a hypocrite who does not recite the Qur’ān is like the colocynth which has no fragrance and has a better taste, and the hypocrite who recites the Qur’ān is like basil whose fragrance is sweet but whose taste is bitter.” A version has, “A believer who recites the Qur’ān and acts according to it is like a citron, and a believer who does not recite the Qur’ān but acts according to it is like a date.” (Bukhārī and Muslim.)
