40-  In the verse 79:30 it is stated that the Earth is egg shape. Eggs are spherical. How Muhammad knew this 1400 years ago?   

The above verse reads: 

Waal-arda baAAda thalika dahaha

It means (word by word):

And the Earth after that was spread.  

Hear are the three famous translations.  

079.030
YUSUFALI: And the earth, moreover, hath He extended (to a wide expanse);
PICKTHAL: And after that He spread the earth,
SHAKIR: And the earth, He expanded it after that. 

Egg in Arabic is “al baiza”. There is no similarity between the two words.  

In Surah 78: 6 it says:

Alam najAAali al-arda mihadan 

Meaning:

Have we not made the earth like a bed?  

078.006
YUSUFALI: Have We not made the earth as a wide expanse,
PICKTHAL: Have We not made the earth an expanse,
SHAKIR: Have We not made the earth an even expanse? 

Arabs used to spread their mattresses (beds) on the floor and sleep on it during the night. In the above verse Muhammad is comparing the Earth to a bed (Mihad) which is spread out. Therefore the translation of the three most reliable interpreters of Quran is correct.  

I think this “egg story” is one of the lies of Rashad Khalifa. I heard that from other submitters. Even so, Earth is not like an egg and an egg is not spherical.  

Muslims are just desperate to fool themselves and any lie will do.
