the Messenger of Allah ﷺ said: “For crops that are irrigated by the sky (i.e. rain) and springs, one-tenth. For those that are irrigated by watering, one half of one-tenth.”  

قَالَ رَسُولُ اللَّهِ ﷺ فِيمَا سَقَتِ السَّمَاءُ وَالْعُيُونُ الْعُشْرُ وَفِيمَا سُقِيَ بِالنَّضْحِ نِصْفُ الْعُشْرِ  

that his Father said: “I heard the Messenger of Allah say: 'For whatever is irrigated by the sky, rivers and springs, or draws up water from deep roots, one-tenth. For whatever is irrigated by animals (i.e. by artificial means) one half of one-tenth.' ”  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ فِيمَا سَقَتِ السَّمَاءُ وَالأَنْهَارُ وَالْعُيُونُ أَوْ كَانَ بَعْلاً الْعُشْرُ وَفِيمَا سُقِيَ بِالسَّوَانِي نِصْفُ الْعُشْرِ  

Mu'adh bin Jabal said: “The Messenger of Allah ﷺ sent me to Yemen and commanded me to take one-tenth of that which was irrigated by deep roots, and to take one half of one-tenth of that which was irrigated by means of buckets.”  

بَعَثَنِي رَسُولُ اللَّهِ ﷺ إِلَى الْيَمَنِ وَأَمَرَنِي أَنْ آخُذَ مِمَّا سَقَتِ السَّمَاءُ أَوْ سُقِيَ بَعْلاً الْعُشْرَ وَمَا سُقِيَ بِالدَّوَالِي نِصْفَ الْعُشْرِ قَالَ يَحْيَى بْنُ آدَمَ الْبَعْلُ وَالْعَثَرِيُّ وَالْعَذْىُ هُوَ الَّذِي يُسْقَى بِمَاءِ السَّمَاءِ وَالْعَثَرِيُّ مَا يُزْرَعُ لِلسَّحَابِ وَلِلْمَطَرِ خَاصَّةً لَيْسَ يُصِيبُهُ إِلاَّ مَاءُ الْمَطَرِ وَالْبَعْلُ مَا كَانَ مِنَ الْكُرُومِ قَدْ ذَهَبَتْ عُرُوقُهُ فِي الأَرْضِ إِلَى الْمَاءِ فَلاَ يَحْتَاجُ إِلَى السَّقْىِ الْخَمْسَ سِنِينَ أَوِ السِّتَّ يَحْتَمِلُ تَرْكَ السَّقْىِ فَهَذَا الْبَعْلُ وَالسَّيْلُ مَاءُ الْوَادِي إِذَا سَالَ وَالْغَيْلُ سَيْلٌ دُونَ سَيْلٍ
