the Messenger of Allah said: "A Ziqq is due for every ten Ziqq of honey."  

رَسُولُ اللَّهِ ﷺ فِي الْعَسَلِ فِي كُلِّ عَشَرَةِ أَزُقٍّ زِقٌّ وَفِي الْبَابِ عَنْ أَبِي هُرَيْرَةَ وَأَبِي سَيَّارَةَ الْمُتَعِيِّ وَعَبْدِ اللَّهِ بْنِ عَمْرٍو  

Nafi said: "Umar bin Adbul-Aziz asked me about charity due on honey, so I said to him: 'We do not have honey that we could give charity from, but Al-Mughirah bin Hakim informed us that he (pbuh) said: 'There is no charity due on honey.' So Umar said: 'That is fair enough for me.' So he wrote to the people that is be lifted, meaning (the duty of paying it) from them."  

قُلْتُ مَا عِنْدَنَا عَسَلٌ نَتَصَدَّقُ مِنْهُ وَلَكِنْ أَخْبَرَنَا الْمُغِيرَةُ بْنُ حَكِيمٍ أَنَّهُ قَالَ لَيْسَ فِي الْعَسَلِ صَدَقَةٌ فَقَالَ عُمَرُ عَدْلٌ مَرْضِيٌّ فَكَتَبَ إِلَى النَّاسِ أَنْ تُوضَعَ يَعْنِي عَنْهُمْ
