وَعَدَدُ الدِّلَاءِ يُعْتَبَرُ بِالدَّلْوِ الْوَسَطِ الْمُسْتَعْمَلِ لِلْآبَارِ فِي الْبُلْدَانِ، فَإِنْ نُزِحَ مِنْهَا بِدَلْوٍ عَظِيمٍ قَدْرَ مَا يَسَعُ مِنَ الدِّلَاءِ الْوَسَطِ: احْتُسِبَ بِهِ
Translation: The bucket count is measured by the medium-sized bucket normally used for wells in each locality. A large bucket counts according to how many medium buckets of water it holds.
The controlling unit is the customary medium bucket and its volume, not simply the number of times a rope is raised.
A large bucket is converted to its equivalent in standard medium buckets.
