"The Messenger of Allah sent me to Yemen and he commanded me to take one-tenth of whatever is irrigated by the sky, and half of one-tenth of whatever is irrigated by means of buckets."  

بَعَثَنِي رَسُولُ اللَّهِ ﷺ إِلَى الْيَمَنِ فَأَمَرَنِي أَنْ آخُذَ مِمَّا سَقَتِ السَّمَاءُ الْعُشْرَ وَفِيمَا سُقِيَ بِالدَّوَالِي نِصْفَ الْعُشْرِ  

Yahya related to me from Malik from a reliable source from Sulayman ibn Yasar and from Busr ibn Said that the Messenger of Allah ﷺ said, "On land that is watered by rain or springs or any natural means there is (zakat to pay of) a tenth. On irrigated land there is (zakat of) a twentieth (to pay)."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ فِيمَا سَقَتِ السَّمَاءُ وَالْعُيُونُ وَالْبَعْلِ الْعُشْرُ وَفِيمَا سُقِيَ بِالنَّضْحِ نِصْفُ الْعُشْرِ  

"The Messenger of Allah sent me to Yemen and he commanded me to take one-tenth of whatever is irrigated by the sky, and half of one-tenth of whatever is irrigated by means of buckets." (Using translation from Nasāʾī 2490)   

«بَعَثَنِي رَسُولُ اللَّهِ ﷺ إِلَى الْيَمَنِ فَأَمَرَنِي أَنْ آخُذَ مِنَ الثِّمَارِ مَا يَسْقِي بَعْلًا الْعُشْرَ وَمَا سُقِيَ بِالسَّانِيَةِ فَنِصْفَ الْعُشْرِ»  

"The Messenger of Allah sent me to Yemen and he commanded me to take one-tenth of whatever is irrigated by the sky, and half of one-tenth of whatever is irrigated by means of buckets." (Using translation from Nasāʾī 2490)  

بَعَثَنِي رَسُولُ اللهِ ﷺ إِلَى الْيَمَنِ «فَأَمَرَنِي أَنْ آخُذَ مِمَّا سَقَتِ السَّمَاءُ الْعُشْرَ وَمِمَّا سُقِيَ بِالدَّوَالِي نِصْفَ الْعُشْرِ»  

"عَنْ مُعَاذٍ قَالَ: بَعَثَنِى رَسُولُ اللهِ ﷺ إِلَى الْيَمَنِ، فَأَمَرَنِى أَنْ آخُذَ مِما سَقَتِ السَّمَاءُ وسُقِىَ بَعْلًا الْعُشْرَ، وَمِما سُقِىَ بِالدَّوَالِى نصف الْعُشْرِ".
