For a long time, especially in the early stages of Islam, the Quran and Muhammad insisted that Islam is just for Arabs and Arabs only! You don’t believe me? Tell me what you get when you read these verses:
“(Mohammed) You are only a Warner and for every nation there is a guide.” (13:7)
“And we have sent no messenger but with the language of his people, that he might make (the message) clear for them.” (14:4)
“He is (Allah) who has raised among the unlettered people a messenger from among themselves” (62:2)
“And thus we have revealed to you an Arabic Quran, so that you may warn the mother of the cities (Makkah) and those around her.” (42:7)
Or course, Abduls will interject and say but but but we have verses say to every one in the following
“It (this Quran) is only a reminder for the Aalameen.” (38:87, 12:104, 6:90, and 81:27)
Aalameen means the world, and everyone. But notice the verses say “reminder”, i.e. a follow up not their book or their message. When compared with the earlier more cut and clear verses.
That is why the Qur’an is very happy to assert:
“Verily, We made it a Quran in Arabic so that you may be able to understand” (43:3)
Did you know that is why for 1350 years it was forbidden to translate the Quran from Arabic! Muslims were forced by necessity to abandon this as many nations and converts found this condition difficult to work with.
