We have revealed for you (O men!) a book in which is a Message for you: will ye not then understand?
The Holy Qur’an is an honour and pride for the Arabs
(a book having a good name for you – 21:10): The word
(Book) is meant for Qur’an and (name) is used here for honour,
excellence and fame. Thus what is meant here is that the revelation of
Qur’an in Arabic language is a great honour and ever lasting fame for
the Arabs and they should value it as such. History has proved that by
Allah’s Mercy and by the blessings of Qur’an Arabs have dominated the
world and ruled over it for a long time. This is also a fact of life that Arabs
gained dominance over the world not because of any tribal or linguistic
supremacy but because of Qur’an. If there was no Qur’an, probably no
one would have known about the Arabs at all.
