The account of the Tower of Babel is recorded in Genesis 11 v 1 – 9: “At one time all the people of the world spoke the same language and used the same words. As the people migrated to the east, they found a plain in the land of Babylonia and settled there. They began saying to each other, ‘Let’s make bricks and harden them with fire.’ (In this region bricks were used instead of stone, and tar was used for mortar.) Then they said, ‘Come, let’s build a great city for ourselves with a tower that reaches into the sky. This will make us famous and keep us from being scattered all over the world.’ But the LORD came down to look at the city and the tower the people were building. ‘Look!’ he said. ‘The people are united, and they all speak the same language. After this, nothing they set out to do will be impossible for them! Come, let’s go down and confuse the people with different languages. Then they won’t be able to understand each other.’
In that way, the LORD scattered them all over the world, and they stopped building the city. That is why the city was called Babel, ‘because that is where the LORD confused the people with different languages. In this way he scattered them all over the world.” God scattered the human race so it could no longer unite in rebellion against God’s plan to redeem mankind. God is certain that when there are so many races, at least some of those races will be humble, and seek the Lord and He will be their God, and they will be a redemptive testimony about Him in the earth. God created so many races to ensure that His kingdom’s mission purpose will be carried out by some races on earth. Those races will take the Good News to the others before Jesus the Messiah returns to earth.
The answer of this question in Islâm is found in Qur’an Surah 49 al-Hujurat ayah 13: ‘Mankind! We have created you from a male and a female, and made you into nations and tribes, that you may know one another. Verily, the most honorable of you with Allâh is that (believer) who has Taqwa (God- consciousness, fearing Allâh). Verily, Allâh is All-Knowing, All-Aware.’
