Yahya related to me from Malik from Abdullah ibn Abi Bakr from his father from Amra bint Abd ar-Rahman that a thief stole a citron in the time of Uthman Uthman ibn Affan ordered its value to be estimated and it was estimated at three dirhams at the rate of exchange of twelve dirhams for the dinar, so Uthman cut off his hand.

The Prophet said, "The example of him (a believer) who recites the Qur'an is like that of a citron which tastes good and smells good. And he (a believer) who does not recite the Qur'an is like a date which is good in taste but has no smell. And the example of a dissolute wicked person who recites the Qur'an is like the Raihana (sweet basil) which smells good but tastes bitter. And the example of a dissolute wicked person who does not recite the Qur'an is like the colocynth which tastes bitter and has no smell.

When the Messenger of Allah (saws) sent him to the Yemen, he said (to him): Collect corn from the corn, sheep from the sheep, camel from the camels, and cow from the cows.

Abu Dawud said: In Egypt I saw a cucumber thirteen spans in length and a citron cut into two pieces loaded on a camel like two loads.

The Prophet said, "The example of a believer who recites the Qur'an and acts on it, like a citron which tastes nice and smells nice. And the example of a believer who does not recite the Qur'an but acts on it, is like a date which tastes good but has no smell. And the example of a hypocrite who recites the Qur'an is like a Raihana (sweet basil) which smells good but tastes bitter And the example of a hypocrite who does not recite the Qur'an is like a colocynth which tastes bitter and has a bad smell."

Allah's Apostle said, "The example of a Believer who recites the Qur'an, is that of a citron which smells good and tastes good; And the example of a Believer who does not recite the Qur'an, is that of a date which has no smell but tastes sweet; and the example of a hypocrite who recites the Qur'an, is that of an aromatic plant which smells good but tastes bitter; and the example of a hypocrite who does not recite the Qur'an, is that of a colocynth plant which has no smell and is bitter in taste."

The Prophet said, 'The example of a believer who recites the Qur'an is that of a citron (a citrus fruit) which is good in taste and good in smell. And the believer who does not recite the Qur'an is like a date which has a good taste but no smell. And the example of an impious person who recites the Qur'an is that of Ar-Rihana (an aromatic plant) which smells good but is bitter in taste. And the example of an impious person who does not recite the Qur'an is that of a colocynth which is bitter in taste and has no smell."

The Prophet (saws) 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.
