There was no "Invasion" of Bahrain in 624 A.D. and the answer to the question never set foot in the country . How can this be acceptable? The tribes of Bahrain accepted Islam and there was a governor appointed and sent to them. That does not mean an invasion. What you might have read on wikipedia about the Al-Kudr is incorrect as that did not have anything to do with the current country of Bharain. It just mentions it was the first interaction with Bahrainis who were an allied tribe to the banu selim. Eastern arabia was called Bahrain at that time. And the invasion of Al Kudr that you see on wikipedia was actually to the north of Medina in a place called Khaybar. Please see https://en.wikipedia.org/wiki/Qarqarat_al-Kudr#:~:text=Qarqarat%20al%2DKudr%20is%20a,watering%20place%20at%20the%20time.
Easy for this former Bahrain resident. Though... is oil really still their most important export? On the one hand, I can't think of anything else they export in any significant quantities, on the other, their oil is almost all used up at this point.
Also, many Bahrainis would contest the answer to the fifth question. And the government does not release official statistics. But it's probably right.
