Ar-Ra'd 13:7

Today, throughout the world, there are more than a billion people who accept the Prophet Muhammad as a prophet of God. But in his lifetime the people of Makkah could not understand that God had made him His prophet. The reason for this was that in the preliminary stage, his prophethood was a controversial issue. But now, in this advanced stage of history, his prophethood is no longer controversial. It is now as easy to believe in the prophethood as it was difficult to believe in it at an earlier, controversial stage. The standards by which the people of Makkah lived were those of wealth, power and popularity. By these standards the Prophet Muhammad did not appear to them to be in any way exceptional, so they wanted him to have some extraordinary sign which would be a definite proof of his prophethood. In response to this it was said that these people demanded something which was not in accordance with God’s plan and as such it would remain beyond human reach. The present world is a place of trial. Here guidance is not available in the form of such clear signs that there is no scope for human doubt, because if that were so, the purpose of the divine test would be defeated. Here the only possibility is for man to take guidance in the shape of ‘information’ and accept it after examining it. One who does not pass this test will never have his share of guidance. God raises in every community a man from among them so that he may deliver the message in a language familiar to them. This arrangement was made for the convenience of the different communities. But it often happened that the communities were affected in the opposite manner: they rejected God’s prophets. Their vision was clouded by the ordinary nature of the messenger. Their eyes could not see the extraordinary nature of the message itself.
