The Qur'an as guidance

يَـٰٓأَيُّهَا ٱلنَّاسُ قَدْ جَآءَكُم بُرْهَـٰنٌ مِّن رَّبِّكُمْ وَأَنزَلْنَآ إِلَيْكُمْ نُورًا مُّبِينًا

O mankind, there has come to you a conclusive proof from your Lord, and We have sent down to you a clear light.

لَقَدْ أَنزَلْنَآ إِلَيْكُمْ كِتَـٰبًا فِيهِ ذِكْرُكُمْ ۖ أَفَلَا تَعْقِلُونَ

We have certainly sent down to you a Book [i.e., the Qur’ān] in which is your mention. Then will you not reason?

وَإِنَّهُۥ لَهُدًى وَرَحْمَةٌ لِّلْمُؤْمِنِينَ

And indeed, it is guidance and mercy for the believers.

هُدًى وَذِكْرَىٰ لِأُو۟لِى ٱلْأَلْبَـٰبِ

As guidance and a reminder for those of understanding.

وَلَوْ جَعَلْنَـٰهُ قُرْءَانًا أَعْجَمِيًّا لَّقَالُوا۟ لَوْلَا فُصِّلَتْ ءَايَـٰتُهُۥٓ ۖ ءَا۬عْجَمِىٌّ وَعَرَبِىٌّ ۗ قُلْ هُوَ لِلَّذِينَ ءَامَنُوا۟ هُدًى وَشِفَآءٌ ۖ وَٱلَّذِينَ لَا يُؤْمِنُونَ فِىٓ ءَاذَانِهِمْ وَقْرٌ وَهُوَ عَلَيْهِمْ عَمًى ۚ أُو۟لَـٰٓئِكَ يُنَادَوْنَ مِن مَّكَانٍۭ بَعِيدٍ

And if We had made it a foreign [i.e., non-Arabic] Qur’ān, 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.

هَـٰذَا بَصَـٰٓئِرُ لِلنَّاسِ وَهُدًى وَرَحْمَةٌ لِّقَوْمٍ يُوقِنُونَ

This [Qur’ān] is enlightenment for mankind and guidance and mercy for a people who are certain [in faith].
