We come to know from different statements of the Quran that this book has been sent for all nations of the world. A similar statement has been made regarding the Prophet in a number of places in the Quran. The following verse is one such example:

“We have sent you as a bearer of glad tidings and a warner for the whole of mankind, but most people have no knowledge.” (34:28)

The Quran is written in Arabic, the language in which it was revealed in Arabia. But as far as its message is concerned it is, in its nature, entirely global and universal. It addresses all the nations of the world rather than any one particular nation.

The basic message of the Quran is that God is One. And it is clear that this is not any temporary or local matter. This is such a fact as concerns all human beings. It has been made clear in the Quran that a man does not die and end forever but that after his death he will be brought to life again and made to stand before God for the final reckoning. This is also such a reality as concerns the whole of humanity. Similarly, it has been enjoined in the Quran that we should adopt the path of justice in our dealings with others. This is also such a teaching as relates to all human beings. Moreover, it has been declared in the Quran that all human beings are the children of one and the same parents, i.e., Adam and Eve, and so all human beings are brothers and sisters to each other. If there is any difference, it is not on the basis of race but on degrees of piety. This is also such a teaching as relates to all human beings. Similarly, all the teachings of the Quran enjoy the position of universality. They provide guidance for all human beings from here to eternity.
