وَكَذَلِكَ الْحِنْطَةُ كُلُّهَا السَّمْرَاءُ وَالْبَيْضَاءُ وَالشَّعِيرُ وَالسُّلْتُ ، كُلُّ ذَلِكَ صِنْفٌ وَاحِدٌ. فَإِذَا حَصَدَ الرَّجُلُ مِنْ ذَلِكَ كُلِّهِ خَمْسَةَ أَوْسُقٍ ، جُمِعَ عَلَيْهِ بَعْضُ ذَلِكَ إِلَى بَعْضٍ ، وَوَجَبَتْ فِيهِ الزَّكَاةُ. فَإِنْ لَمْ يَبْلُغْ ذَلِكَ فَلَا زَكَاةَ فِيهِ
Imam Malik, may Allah have mercy on him, said: If there are several types of dates, each with a different name, then all of them will be combined, and those with skin and without skin that are considered the same will also be combined. When the total reaches five wasq, zakat will be obligatory; otherwise, it will not be obligatory.
