It was narrated from Amr bin:
Shu'aib, form his father, that his grandfather said: “The Messenger of Allah only prescribed Zakat on these five things: wheat, barley, dates, raisins and corn.”

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَيَّاشٍ، عَنْ مُحَمَّدِ بْنِ عُبَيْدِ اللَّهِ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ إِنَّمَا سَنَّ رَسُولُ اللَّهِ ـ ﷺ ـ الزَّكَاةَ فِي هَذِهِ الْخَمْسَةِ فِي الْحِنْطَةِ وَالشَّعِيرِ وَالتَّمْرِ وَالزَّبِيبِ وَالذُّرَةِ .
