What happened when Bahrain, Saudi Arabia, and Egypt severed diplomatic relations with Qatar?

Qatar, Saudi Arabia, and Bahrain belong to the six Gulf countries. They are all Sunni, and Saudi Arabia is the leader.

Qatar is relatively open. Al Jazeera is located in Qatar and is the most influential TV station in Arab countries. Then, it was exposed that Qatar wanted to develop relations with Iran.

The problem is that Iran is the leader of the Shiite sect and is at odds with Saudi Arabia. So Saudi Arabia became furious and announced the severance of diplomatic relations. Bahrain is experiencing domestic instability and needs Saudi Arabia to protect it and follow up on the severance of diplomatic relations. Egypt needs Saudi Arabia's assistance to solve the domestic food problem. It doesn't hurt the bones and muscles to break off diplomatic relations, so just break it off.
