عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ لَا يَسُبَّ أَحَدُكُمُ الدَّهْرَ فَإِنَّ اللَّهَ هُوَ الدَّهْرُ وَلَا يَقُولَنَّ أَحَدُكُمْ لِلْعِنَبِ الْكَرْمَ فَإِنَّ الْكَرْمَ هُوَ الرَّجُلُ الْمُسْلِمُ
Syedna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: No person should curse time, for Allah Almighty is time; and no person should call grapes "karam," for "karam" is a Muslim person.
