وَعَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ عَنِ
النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «فِيمَا سَقَتِ السَّمَاءُ وَالْعُيُونُ أَوْ كَانَ عَثَرِيًّا الْعُشْرُ. وَمَا سقِِي بالنضح نصف الْعشْر»
Abdallah ibn Umar reported the Prophet (sallallahu alayhi wa sallam) as saying, “A tenth is payable on what is watered by rain or wells, or from underground moisture, and a twentieth on what is watered by draught camels.”
