Very interesting facts from Astronomers & Scientists.. I still could not get it about fact number 18 ? Half of the stars are visible at daylight with naked eye from Earth? Could anyone explain!

Australian guy become a Muslim

While browsing on Youtube, I found these videos and thought of sharing it.. This is a MUST watch.. Part 2 is the most interesting one.

Part 1


Part 2

Click here for Arabic Translation 2nd part only

In part 2: I liked when he said: “ For those of you ask for signs have We not shown you enough already? look around you. look at the stars look at the sun and look at the water. these are the signs of the people of knowledge “.

He didn’t mention the verse.. but anyway the verse is @ Surah Al-Baqara Verse 164 >>> The Holy Qur’an

Looks he read a different English translation of the Qur’an. Because all translations are from different people.  Anyway Good point.
