Response: Makes perfect sense. If you speak to a people, you speak in their language. Since Muhammad(pbuh) is an arab amongst arab people who speaks arabic, yes it makes perfect sense for the revelation to be in arabic.
Agreed
What doesn't make sense is when someone uses this logical concept as some sort of proof that the qur'an, the challenge, or the religion of islam is supposed to be just for the arabs when neither the qur'an, the challenge, or the religion of islam says so, nor can you or anyone else show otherwise.
No,all i said was the challenge isn't universal.
But what we do find in the qur'an is clear cut language that says: O mankind, truly I am a Messenger to you all from Allah to whom belongs the Kingdom of the heavens and the earth. There is no god but He. He gives life and He causes death. So believe in Allah and his Messenger, the unlettered Prophet, who believes in Allah and His words; and follow Him that you may be rightly guided".
Ch.7:158
From this verse, we can clearly see that the message is to all of mankind, not just the arabs.
