Lady Aisha Siddiqa (may Allah be pleased with her) narrates: Whoever tells you that the Prophet Muhammad (peace and blessings be upon him) used to urinate standing up, then declare him a liar, because I always saw him urinating while sitting. (Imam Ibn Hibban, may Allah have mercy on him, says:) This narration has caused confusion for the one who does not have expertise in the knowledge of hadith, and he thought that it contradicts the narration transmitted from Sayyiduna Hudhaifa (may Allah be pleased with him), which we have mentioned earlier. However, this is not the case, because Sayyiduna Hudhaifa (may Allah be pleased with him) saw the Prophet Muhammad (peace and blessings be upon him) urinating by a wall near a heap of garbage, and this was at the outskirts of Madinah Munawwarah, and we have already explained the reason for this action of the Prophet (peace and blessings be upon him). Lady Aisha (may Allah be pleased with her) was not with the Prophet (peace and blessings be upon him) at that time. Lady Aisha (may Allah be pleased with her) saw the Prophet (peace and blessings be upon him) urinating while sitting at home, so she narrated what she had seen, but Sayyiduna Hudhaifa (may Allah be pleased with him) narrated what he had seen. Therefore, Lady Aisha’s (may Allah be pleased with her) statement, "declare him a liar," means that you should consider him mistaken, because sometimes the Arabs use the word "lie" (kathib) to mean "mistake."
