HAKIM 1458:
from Muʿādh b. Jabal —
[Machine] The Messenger of Allah ﷺ said, "Regarding what is watered by rain, natural springs, and the overflow of rivers, one-tenth (of the crops) is due. And regarding what is watered through irrigation channels, half of one-tenth (of the crops) is due. This applies only to dates, wheat, and grains. As for cucumbers, watermelons, pomegranates, and sugarcanes, the Messenger of Allah ﷺ exempted them from this."
الحاكم ١٤٥٨:
عن معاذ بن جبل —
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «فِيمَا سَقَتِ السَّمَاءُ وَالْبَعْلُ وَالسَّيْلُ الْعُشْرُ وَفِيمَا سُقِيَ بِالنَّضْحِ نِصْفُ الْعُشْرِ وَإِنَّمَا يَكُونُ ذَلِكَ فِي التَّمْرِ وَالْحِنْطَةِ وَالْحُبُوبِ وَأَمَّا الْقِثَّاءُ وَالْبَطِّيخُ وَالرُّمَّانُ وَالْقَصَبُ فَقَدْ عَفَا عَنْهُ رَسُولُ اللَّهِ ﷺ»
