Fussilat, 44 Ayah
41:44
وَلَوۡ جَعَلۡنَٰهُ قُرۡءَانًا أَعۡجَمِيّٗا لَّقَالُواْ لَوۡلَا فُصِّلَتۡ ءَايَٰتُهُۥٓۖ ءَا۬عۡجَمِيّٞ وَعَرَبِيّٞۗ قُلۡ هُوَ لِلَّذِينَ ءَامَنُواْ هُدٗى وَشِفَآءٞۚ وَٱلَّذِينَ لَا يُؤۡمِنُونَ فِيٓ ءَاذَانِهِمۡ وَقۡرٞ وَهُوَ عَلَيۡهِمۡ عَمًىۚ أُوْلَٰٓئِكَ يُنَادَوۡنَ مِن مَّكَانِۭ بَعِيدٖ ٤٤
Wa Law Ja`alnāhu Qur'ānāan 'A`jamīyāan Laqālū Lawlā Fuşşilat 'Āyātuhu ۖ 'A'a`jamīyun Wa `Arabīyun ۗ Qul Huwa Lilladhīna 'Āmanū Hudáan Wa Shifā'un Wa ۖ Al-Ladhīna Lā Yu'uminūna Fī 'Ādhānihim Waqrun Wa Huwa `Alayhim `Amáan 'Ūlā'ika ۚ Yunādawna Min Makānin Ba`īdin
And if We had made it a non-Arabic Qur'an, they would have said, "Why are its verses not explained in detail [in our language]? Is it a foreign [recitation] and an Arab [messenger]?" Say, "It is, for those who believe, a guidance and cure." And those who do not believe - in their ears is deafness, and it is upon them blindness. Those are being called from a distant place.
