Undesirability of Calling Grapes ‘Al-Karm’
1740. Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah (sallallaahu alayhi wa sallam) said, “None of you should use the word Al-Karm for grapes, for Al-Karm is a Muslim (worthy of respect).”
[Al-Bukhari and Muslim]
Another narration is: “Verily, Al-Karm is the heart of a true believer.”
Another narration is: “People have named grapes as Al-Karm; verily, only the heart of a believer is Al-Karm.”
1741. Wa’il bin Hujr (May Allah be pleased with him) said: The Prophet (sallallaahu alayhi wa sallam) said, “Do not say Al-Karm when talking about grapes but say Al-`Inab or Al-Habalah.”
[Muslim].
