- "(Mohammed) You are only a Warner and for every nation there is a guide."(13:7)
The principle given by the Quran here proves that as per his own standards Mohammed can only be a guide for his nation i.e. Arabs.
- "And we have sent no messenger but with the language of his people, that he might make (the message) clear for them." (14:4)
This principle also proves that as per his own standards Mohammed can only be a guide for Arabic speaking people.
- "He is (Allah) who has raised among the unlettered people a messenger from among themselves" (62:2)
So Mohammed claims only to be a prophet for "Umeen" the unlettered people of Arabia.
It is also interesting to note here that "Umeen" could also mean people of Makkah (note-4).
- "And this (Quran) is a blessed book which we have revealed, confirming that which was (revealed) before it, so that you (O prophet) may warn the mother of the cities (Makkah) and those around her." (6:92)
"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)
The above verses clearly show that Mohammed claims to have received a revelation in Arabic to warn people of Makkah and those living close to it, of course the Arabic speaking people.
