Hadith That A Baby Boy's Urine Is Pure But A Baby Girl's Urine Is Impure
Any person, even a Prophet, lives within bounds of the worldly knowledge of their time unless something is revelaed to them by Allah which is very rare because their primary responsibility is to divulge the news of Akhirah or in other words, the message of God. Just because they are prophets, it does not mean they are taught all the laws which govern this universe. In worldly matters, there are plenty of examples that prophets rely on the available knowledge of their time to make wordly decisions, with the only excpetion when God intervenes because of something which directly relates to the mission of Prophets. There are many examples where Prophet Muhammad (sws) gave opinions of worldly matters which are not scientifically true today but were known to be true by the human knowledge of that time. In one incident of cross-pollination of medina , his opinion was in contradiction to the already established science of that time. Simialrly, we see matters of medicine of the Prophet (sws) famously known as Tibb-e-Nabwi which has no scientific basis today but was knowledge of that time, similarly hadith about not sleeping in one specific posture etc etc. When solar eclispe happened in Medina, Prophet (sws) under apprehension that maybe God had made a decision against his nation, offered long Salah of eclipse to seek God’s mercy until the time solar eclipse vanished. This specific Hadith only seems contentious because we are studying it in the light of today’s knowledge. It was a simple expression of knowledge of that time and does not have to do with girl or boy per se, but with the understanding of the anatomy of baby boy and baby girl. And it must be kept in mind that it is only the infants which are being discussed here, not the adults. Had there been some violation of kindness and wisdom on the part of Prophet Muhammad (sws), then the same would have extended to adults as well, which seems to not be the case because as said earlier, it has more to do with the knowledge of that time. Now there can be two approaches that can be followed in this regard: i ) To see it in the context explained above. ii ) to outright reject it as saying of the Prophet (sws) We do not follow this approach where we easily put a Hadith in abeyance specially when the chain seems to be reliable and the content can be easily understood in the light of the Hadith Principles.
