What if Jesus had given birth just like other Prophets of God that came before him, is his son to be God's begotten grandson since the father is the only begotten son of God?

Are we actually instructed to celebrate Christmas in the book?
If the answer is yes, are there guides for it celebration in the book just like in other religions.

Is there any clear instructions that says we should be going to Jerusalem for pilgrimage? If the answer is yes, do we have guides for how it will be performed so it can become acceptable to God in heaven.

Since polygamy is condemned in the bible, is there a passage that contains information about punishment for offenders?
Since the creator knows that he will create more females than male, did he want some females to remain unmarried for the rest of their lives?

I trust your knowledge and intelligence, help a brother.
