As the Word of Allah Almighty in the Al Qur’an at Surah Suad, verse 29:
كِتٰبٌ اَنْزَلْنٰهُ اِلَيْكَ مُبٰرَكٌ لِّيَدَّبَّرُوْۤا اٰيٰتِهٖ وَلِيَتَذَكَّرَ اُولُوا الْاَلْبَابِ
“(This is) a Book (the Quran) which We have sent down to you, full of blessings that they may ponder over (conduct research) its Verses, and that men of understanding may remember.”
Based on the verse above, if we conduct scientific research in the field of medical knowledge about the commands of Allah Almighty, in the Al Quran, Surah Al Baqarah verse 168, that said: “O mankind, eat from whatever is on earth [that is] lawful and good and do not follow the footsteps of Satan. Indeed, he is to you a clear enemy.”
Then, Allah (S.W.T) in Al Qur’an said that:
“Who enjoins upon them what is right and forbids them what is wrong and makes lawful (halal) for them the good things and prohibits for them the evil and relieves them of their burden and the shackles which were upon them.”
At the Surat Al Baqarah, verse 168 above, Allah Almighty not only calls Muslims but to all mankind to consume foods that halalan thoyyiban (lawful and good) This proves that Islam is a mercy to all the worlds (Rahmatan lil Alamin)This is strengthened by the Hadith the prophet who said that: “The main source of various diseases is the stomach. Stomach is a repository of illness and fasting it is the cure.” (Hadith narrated by Muslim).
Islamic Shariah about the obligation to consume halal food should be verified and proved about the truth. Therefore, Allah Almighty has instructed us to examine the truth of the verses Allah Almighty, as Allah Almighty commanded in Surah Sad, verse 29 mentioned above. Experts should be able to prove this, because Allah Almighty has promised to prove the truth of the verses of Allah Almighty, as the promise of Allah Almighty in surah Fushilat verse 53.
“We will show them Our Signs in the universe, and in their ownselves, until it becomes manifest to them that this (the Quran) is the truth. Is it not sufficient in regard to your Lord that He is a Witness over all things.”
Based on verses of the Al Quran and the Hadith mentioned above, it will explain the suitability of Islamic teachings with medical science, about the dangers of consuming haram foods and beverages on physical and spiritual health.
