Which one is the first Muslim country in world?

Answer 1

It is Saudi Arabia. Yes it is indeed Saudi Arabia, where the Prophet Muhammad SAW was born, raised and was ordained by Allah through His Arch Angel Jibril (Gabriel) as His last Prophet or Messenger when he was 40 years old. He subsequently went on to spread the messages of Allah (revealed to him in God's words by Jibril) to the Arabs of the Arabian peninsular from Mecca right up to Medinah, over a period of 23 years. Finally the majority of the Arabian peninsular state population embraced Islam as the only faith and the first Muslim nation was born. Muhammad SAW became the first head of state of this first Islamic nation with the Syariah laws implemented nationwide.
