Narrated Abu Musa Al-Ash`ari: 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.

Narrated Ibn `Umar: The Prophet said, "Your life in comparison to the lifetime of the past nations is like the period between the time of `Asr prayer and sunset. Your example and the example of the Jews and Christians is that of person who employed laborers and said to them, "Who will work for me till the middle of the day for one Qirat (a special weight)?' The Jews did. He then said, "Who will work for me from the middle of the day till the `Asr prayer for one Qirat each?" The Christians worked accordingly. Then you (Muslims) are working from the `Asr prayer till the Maghrib prayer for two Qirats each. They (the Jews and the Christians) said, 'We did more labor but took less wages.' He (Allah) said, 'Have I wronged you in your rights?' They replied, 'No.' Then He said, 'This is My Blessing which I give to whom I wish."
