Prophetic Medicine places particular emphasis on hygiene, and the Prophet ﷺ recommended that we wash and remove hair at certain areas of the body. Soaps such as camel milk soap or pure black seed soap are recommended, and as for hair removal, this helps prevent the buildup of bacteria linked to unpleasant odors.
In addition, the Sunnah teaches us to wear loose-fitting clothing, ideally made of natural fibers.
Also, an important point that many of us overlook: excessive sweating can come from stress. So before reaching for deodorants, one can practice regular physical activity such as walking or running, and take natural calming remedies such as linden herbal tea.
As an underlying treatment, lemon juice helps block the appearance of bad odors. Cucumber, a food appreciated by our Prophet ﷺ, has astringent properties; it will therefore close the pores and can be eaten in a salad or as a juice.
In addition, apple cider vinegar can be applied locally in the evening with a cotton pad to neutralize bacteria.
A pore-tightening cream based on aloe vera can also help, and this will also regulate the skin's pH while hydrating it.
Finally, medical tests will help rule out any hormonal issue.
What the science says: hydration and heat
What published research says about the remedies mentioned above, for context — the studies address material causes, while healing belongs to Allah.
Hydration and heat
Drinking enough water supports the kidneys and digestive transit (Am J Clin Nutr, 2022) and prevents urinary stones (Minerva Urol Nephrol, 2025); in very hot weather, water, water-rich fruits (watermelon, cucumber — favorites of the professor), shade, and rest during the hottest hours help prevent heatstroke. The Sunnah recommends drinking while seated, in three sips, without excess ice. Precaution: infants, the elderly, and people with chronic illness become dehydrated quickly; confusion, absence of urination, or a high temperature during a heatwave are warning signs.
