Do not say al-karm (for the word vine) but say al-habala (that is grape).  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ تَقُولُوا الْكَرْمُ وَلَكِنْ قُولُوا الْحَبَلَةُ يَعْنِي الْعِنَبَ  

This hadith has been reported by Alqama b. Wa'il on the authority of his father with a different chain of transmitters and with a slight variation of wording.  

أَنَّ النَّبِيَّ ﷺ قَالَ لاَ تَقُولُوا الْكَرْمُ وَلَكِنْ قُولُوا الْعِنَبُ وَالْحَبَلَةُ  

[Machine] "Allah's Messenger ﷺ said: 'Do not say 'generosity,' say 'grapes' or 'vines.'"  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَا تَقُولُوا الْكَرْمَ وَقُولُوا الْعِنَبَ أَوِ الْحَبَلَةَ  

Do not say al-karm (for the word vine) but say al-habala (that is grape). (Using translation from Muslim 2248a)  

عَنِ النَّبِيِّ ﷺ قَالَ «لَا تَقُولُوا الْكَرْمُ وَلَكِنْ قُولُوا الْحَبَلَةُ أَوِ الْعِنَبُ»  

[Machine] The Messenger of Allah ﷺ said, "Do not say 'grape' but say 'vine' or 'grapevine'."  

قَالَ رَسُولُ اللهِ ﷺ «لَا تَقُولُوا لِلْعِنَبِ الْكَرْمَ وَلَكِنْ قُولُوا الْحَبَلَةَ أَوِ الْحَبَلَ»
