1. We eat 1 meal a day with nothing in between but coffee (a powerful detoxifier and laxative) or possibly a little water, and fast 3 days every month. The mainstream now calls this "intermittent fasting". It is a process of constant detoxification that allows "toxins" (poison/waste) to be eliminated instead of accumulating to harmful levels. Knowledge of what and how to eat keeps us healthy and off medications (which may be impossible to get in an emergency).
2. Our bodies are immaculately clean. We take a minimum of one proper bath per day as well as washing up before prayer (at least 5 times daily). During this time our face, ears, nose, mouth, hands, arms, legs, feet, etc. are all washed. These areas, especially the face and hands, are how most diseases are spread. We keep our nails short which keeps germs from accumulating there and being transferred into food, onto surfaces, etc. Whether we use toilet paper or not, we wash with soap and water after using the bathroom.
3. Our homes are exceptionally clean. We do not let dust (dirt) accumulate. Our kitchens and bathrooms are washed meticulously on a daily basis. We wash grocery packaging before storing them away. We air out our homes regularly and use bleach in heavy cleaning and in dishwater. This prevents the spread of germs and ensures sanitary food, air quality, etc.
4. We tend to burn incense, diffuse aromatherapy, etc. which cleanses the air. It also helps build immunity by improving the "mood/emotional state" of those we we welcome into our homes.
5. We do not wear shoes in the home. All those germs that collect from walking in public places are not dragged into our home to be trapped in carpet or smeared on tile and wood. We prefer solid flooring to carpet because it allows deeper cleaning, but if we have carpet we clean it often.
6. We wear long clothes. Just as you see doctors wearing long coverings and hats for protection, so do we. When we come home, we usually change out of our "outdoor clothes" which have protected our skin and hair from outdoor germs and pollution.
7. We don't socialize much outside or in crowds. Most of our entertaining is done among those in our brotherhood/sisterhood who share the same hygienic practices as us. We entertain at home. We don't go to germ-infested movie theaters where we would have to worry about getting shot by mentally unstable people, etc.
8. We don't eat pork or food cooked by those who do. The trichinae worm can be passed into food on hands that have not been thoroughly washed after using the bathroom. This means we don't eat at restaurants often.
BTW:If you eat pork, Corona is the least of your problems lol.
9. We understand that grocery store supplies are always limited and act accordingly. Read that again.
10. We know how to take instructions (as long as they don't conflict with our religion). We don't act in ways that will put ourselves and our families in harm's way. We act intelligently, although we know how to have fun. We understand there is a time and place for everything.
11. We do not eat while “walking down the street”. Eating outside exposes the eater to ingesting pollution and germs along with the food (dirt blows). Also, it poses the issue of proper hand washing for the eater, and if the food is prepared outside, for the cook as well. It is nearly impossible to protect the hygiene of your food when carelessly eating on the go. It is an extremely unnatural practice that makes digestion difficult.
Those are just a few things that came to mind. There are more. When I say our culture is our immune system, I mean just that. Our way of life is a protective barrier that others can learn from, if they so choose. It is an immunity more Muslims would benefit from if we were more willing to submit. If you see an NOI Muslim looking like everyone else, they have chosen to live outside of their culture for a period of time. It is not a reflection of the effectiveness of the NOI lifestyle, but a mere indicator of their poor choices and weaknesses.
All praise is due to Allah who came in the person of Master Fard Muhammad.
