my answer referring to stories about prophet muhammad is deleted. and why it is deleted? a comment refers to meta q. #112 and i think this is not enough to delete it, because
- it is just a question and answer, it is not site's faq
- this question is only about reliable sources, but if you look at another question to which it refers, #1, most voted answers say: "Perhaps if a thorough enough answer is given, a reference wouldn't be required, but usually it would", "It doesn't even have to be a totally irrefutable source; it can range from believable to reputable to trust-worthy to actual evidence.", so it is voted to allow not only that scientific links, but just some links should be, or at least thorough answer (without links)!
- the answer to q. 112 with most votes, linking to scientific sites, says "Note that this is not a whitelist".
- the idea in this hadith is very simple and straightforward. no food and no water may work as a trigger meaning no resourses to use for pregnancy and child growth, and even as no resourses for sperm production, so it should deactivate/passivate sexual desire. and the answer in q. 112 says "We should downvote if there are no sources, unless it is widely known (for example, the statement "If you get too cold you die" is a little unnecessary to backup. The actual temperature (35 C and less) should be linked.".
