Asalaam
alaikum Warahmatulah Wabarakatuh.
An Arabic
Qur'an...
Allah tells us continuously that the
Qur'an is in the Arabic language, a response to those who might argue
that translations in other languages can be a replacement.
So
we notice that whenever Allah mentions the Qur'an in a language, it
is none other than Arabic;
إِنَّا أَنزَلْنَاهُ قُرْآنًا عَرَبِيًّا لَّعَلَّكُمْ تَعْقِلُونَ
Indeed, We have sent it down as an Arabic Qur'an [Qur'anan 'arabiyyan] that you might understand.
[Yusuf 12:2]
وَكَذَٰلِكَ أَنزَلْنَاهُ حُكْمًا عَرَبِيًّا
And thus have We sent it (the Quran) down to be a judgement of authority in Arabic.. [hukman arabiyyan].
[ar-Ra'd 13:37]
وَكَذَٰلِكَ أَنزَلْنَاهُ قُرْآنًا عَرَبِيًّا
And thus We have sent it down as an Arabic Qur'an [qur'anan 'arabiyyan].. [Qur'an Taha 20:113]
Also see
the ayaat/verses in Surahs to prove this further;
