وَمِائَتَا دَلْوٍ لَوْ لَمْ يُمْكِنْ نَزْحُهَا
• The matn gives 200 customary medium buckets when complete drainage of the small well is impossible because water continually replenishes.
• The commentary records this as the estimate of Imam Muhammad and also mentions another method in which knowledgeable persons estimate the amount of water in the well.
• Therefore, 200 buckets should be understood as the specific rule stated in the matn, not as a universal modern volume for every well.
