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  

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  

[Machine] As for what the sky provided and what was watered, it opened up tenfold and was not watered by a bucket, but by half of the ten.  

فِيمَا سَقَتِ السَّمَاءُ وَمَا سُقِيَ فَتْحًا الْعُشْرُ وَمَا سُقِيَ دَلْوًا فَنِصْفُ الْعُشْرِ  

"عَنْ عُمَرَ قَالَ: فِيمَا سَقَتِ السَّمَاءُ وَالأَنْهَارُ وَالعُيُونُ العُشْرُ، ومَا سُقِى بالرَّشَا (*) نِصْفُ العُشْر".  

"عَنْ عليٍّ قَالَ: فِيمَا سَقَتِ السَّمَاءُ الْعُشْرُ، وَإِذَا سُقِىَ بِالدَّوَالِى وَالنَّواضِح نِصْفُ الْعُشْرِ".  

"عَنْ قَتَادَةَ، عَنْ أَنَسٍ قَالَ: سَنَّ رسُولُ الله ﷺ فِيمَا سَقَتِ السَّمَاءُ وسَقَى السَّيْحُ، وسقى الْغَيْل الْعُشْرَ، وَمَا سُقِىَ بِالرِّشَاءِ فَنِصْف الْعُشْرِ".  

"فِيمَا سَقَتِ السَّمَاءُ العُشْرُ، وَمَا سُقِيَ بِالْعَرْبِ وَالدَّالِيَةِ فَفِيهِ نِصْفُ العُشْرِ".
