وَنُنَزِّلُ مِنَ ٱلْقُرْءَانِ مَا هُوَ شِفَآءٌ وَرَحْمَةٌ لِّلْمُؤْمِنِينَ ۙ وَلَا يَزِيدُ ٱلظَّٰلِمِينَ إِلَّا خَسَارًا
10:58; 12:112; 16:90.
Commentary:
The verse purports to say that as to a jaundiced eye all objects appear yellow, similarly to a mind which is swayed by jealousy and prejudice, even most pure and noble teachings appear impure and ignoble. Such was the case with disbelievers in regard to the teachings of the Quran.
The word "Quran" in this verse may also be taken to refer to the portion of the Quran already revealed, the portion containing prophecies about the prosperity and success of the Faithful and the ruin and destruction of disbelievers. The verse means to say that the time has come for the fulfilment of those prophecies and that the flight of the Prophet from Mecca would usher in an era of triumph for Islam and would bring discomfiture and humiliation to disbelievers.
