Qatadah (may Allah have mercy on him) said: I mentioned the statement of Jabir bin Zayd (may Allah have mercy on him) to Sa'id bin al-Musayyib (may Allah have mercy on him), so he said: "What if he urinates from both passages at the same time?" I said: "I do not know." So he said: "The ruling will be according to whichever side it comes from first."
