Hadith are the words, deeds, and confessions of the prophet Muhammad SAW since 14 centuries ago, which have many benefits for life, have secrets that are only recently known today. Hadiths related to daily life include food, drink, health, and sleep. These secrets can be studied from various angles, the chain, the book, and the secrets of science contained include physics, chemistry, biology, and medicine. The secrets that can be deepened are siwak, fasting, good sleep, prohibition to eat animal flesh with fangs and claws.
1. Siwak
The prophet's instructions are an appeal to use siwak when they want to pray. Laboratory studies prove that miswak comes from the fig tree which contains several chemical compositions to protect teeth from brittleness and decay, and treat gums from inflammation. The other composition consists of pepper oil and grape sugar which has a biting taste and pungent aroma. These two compositions can function to kill germs in the mouth.
2. Fasting
The results showed that fasting people had better physical performance than non-fasting people. Fasting is also useful for improving the level of endurance, improving the performance of the liver and heart, and other systems while fasting. Fasting can also melt fat in the body so that it adds hot fatty acids in the blood. And when fasting the body starts the cleaning process that has accumulated such as fat, dirt, viruses, toxins, and germs that can harm the body if it gets buried.
3. How to sleep well
Sleeping facing the right is a good sleeping position, because the left lung is smaller than the right lung, so it puts very little emphasis on the heart, and the liver does not burden the stomach so that the stomach can be emptied immediately. According to medicine, sleeping on the right side facilitates the removal of mucus secretions in the left respiratory bronchioles. By sleeping on the right, the head is facing north, the feet are facing south, and the face is facing the Qibla, so that the body does not resist the current from the constant magnetic field that flows throughout the body.
4. Prohibition of eating animal flesh with fangs and claws
The prohibition or prohibition is the same as the prohibition of carrion and blood. Because animals that die not because of slaughter factors can be caused by organic diseases or viruses that afflict these animals. Thus, consuming animal meat that is not from the slaughter factor can cause direct transmission of viruses that carry diseases and deadly chemical elements.m
