Sunan Abi Dawud 4829

Narrated Anas ibn Malik: The Prophet (ﷺ) said: A believer who recites the Qur'an is like a citron whose fragrance is sweet and whose taste is sweet, a believer who does not recite the Qur'an is like a date which has no fragrance but has sweet taste, a profligate who recites the Qur'an is like basil whose fragrance is sweet but whose taste is bitter, and the profligate who does not recite the Qur'an is like the colocynth which has a bitter taste and has not fragrance. A good companion is like a man who has musk; if nothing of it goes to you, its fragrance will (certainly) go to you; and a bad companion is like a man who has bellows; if its (black) root does not go to you, its smoke will (certainly) go to you
