وَالسُّنَّةُ عِنْدَنَا فِي الْحُبُوبِ الَّتِي يَدَّخِرُهَا النَّاسُ ، وَيَأْكُلُونَهَا أَنَّهُ يُؤْخَذُ مِمَّا سَقَتْهُ السَّمَاءُ مِنْ ذَلِكَ ، وَمَا سَقَتْهُ الْعُيُونُ وَمَا كَانَ بَعْلًا الْعُشْرُ وَمَا سُقِيَ بِالنَّضْحِ نِصْفُ الْعُشْرِ إِذَا بَلَغَ ذَلِكَ خَمْسَةَ أَوْسُقٍ بِالصَّاعِ الْأَوَّلِ ، صَاعِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، وَمَا زَادَ عَلَى خَمْسَةِ أَوْسُقٍ فَفِيهِ الزَّكَاةُ بِحِسَابِ ذَلِكَ .
He said: For all types of grains which people eat or store, if they are produced by rainwater or spring water, or if they do not require irrigation, then one-tenth is obligatory. And for those which are irrigated, one-twentieth is obligatory, when they reach the amount of five wasq, each wasq being sixty sa’ according to the sa’ of the Prophet, peace be upon him. And if it is more than this, then zakat will be taken according to the same calculation.
