How could he have known this?

@fouzsami الله أكبر There are thousands of evidences which prove that the Messenger of Allah صلى الله عليه وسلم came with the absolute truth, and whatever opposes that truth is falsehood.

1. First of all, this proves God(Allah) exist. 2. Second, this proves that the prophet was truthful one sent by God. 2. Third, this proves that the Quran and Hadith have true knowledge reveal by Allah. 4. This means if all of above are true then Islam is the ultimate truth!

It’s in the Hadith

if a fly falls in the vessel anyone of you, let him dip all of it (in the vessel) and then throw it away, for in one of its wings has the ailment and the other has the cure" (Al-Bukhari).

Can I get a link to the official study please?

There is no deity except Allah. Prophet Muhammad (peace be upon him) is, like other prophets, His servant and messenger.

There are more and more of these recent scientific discoveries that were mentioned in the Quran or Hadith of the Prophet of Islam

فَبِأَىِّ ءَالَآءِ رَبِّكُمَا تُكَذِّبَانِ Then, which of the blessing of your Lord will you deny

Revelation from the all mighty Allah, this shouldn't surprise Muslims and should make non-believers think deeply and consider the evidence for Islam
