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  

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

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

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

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