[Machine] The Messenger of Allah ﷺ stated, "It is obligatory to give one-fortieth (2.5%) of the wealth, and of what is watered by the rivers and rainfall, one-half of the tenth (5%)."
أَنَّ رَسُولَ اللهِ ﷺ «فَرَضَ فِي الْبَعْلِ وَفِيمَا سَقَتِ الْأَنْهَارُ الْعُشُورَ وَمَا سُقِيَ بِالنَّضْحِ نِصْفَ الْعَشْرِ»
