Both reports are essentially one and cannot be used to reject all the other narrations. If we act according to the previous narrations, we would still be acting in accordance with these two reports as well. This is because when all the water is drawn out or a volume equivalent to a kurr is removed, it already includes the requirement of thirty buckets. However, if we act solely based on these two reports, we would be rejecting the other narrations entirely and ignoring their rulings. As for the consideration of four men alternating to draw water when it becomes difficult to empty it completely, this is supported by the narration we previously mentioned from Amr ibn Sa'id, from Ibn Hilal. He said: I asked Abu Ja'far عليه السلام about things that fall into a well, listing them until I mentioned a donkey or a camel. Imam عليه السلام said: "A kurr of water." When the quantity is large, four men should alternate to draw water for a day, which amounts to more than a kurr and does not fall short. This should suffice. Alternating the men is applicable in cases where something falls into the water and alters its color or taste, making it difficult to remove all of it.
