if you dont have an answer for this, then keep quite, dont advertise your ignorance all around, I have replied you for this below.
I know, quran does not have answers to all this, basically MohMad only copeid data that he could understand and the rest he just left uncopied because it was too complex for him to understand.
You see, your comrade Dr Naik has confessed himself in a video posted on youtube that MohMad's father was a brahmin and priest at the shiva temple in Mecca when he was trying to prove that Mohmad is kalki avtaar.
Dont try to protect the hoax, if you say, you are a man with scientific bent of mind, then come back to hindusim
