وَمَا كُنْتَ تَتْلُو مِنْ قَبْلِهِ مِنْ كِتَابٍ وَلَا تَخُطُّهُ بِيَمِينِكَ ۖ إِذًا لَارْتَابَ الْمُبْطِلُونَ ٤٨
And thou wast not (able) to recite a Book before this (Book came), nor art thou (able) to transcribe it with thy right hand: In that case, indeed, would the talkers of vanities have doubted.
بَلْ هُوَ آيَاتٌ بَيِّنَاتٌ فِي صُدُورِ الَّذِينَ أُوتُوا الْعِلْمَ ۚ وَمَا يَجْحَدُ بِآيَاتِنَا إِلَّا الظَّالِمُونَ ٤٩
Nay, here are Signs self-evident in the hearts of those endowed with knowledge: and none but the unjust reject Our Signs.
وَقَالُوا لَوْلَا أُنْزِلَ عَلَيْهِ آيَاتٌ مِنْ رَبِّهِ ۖ قُلْ إِنَّمَا الْآيَاتُ عِنْدَ اللَّهِ وَإِنَّمَا أَنَا نَذِيرٌ مُبِينٌ ٥٠
Ye they say: "Why are not Signs sent down to him from his Lord?" Say: "The signs are indeed with Allah: and I am indeed a clear Warner."
أَوَلَمْ يَكْفِهِمْ أَنَّا أَنْزَلْنَا عَلَيْكَ الْكِتَابَ يُتْلَىٰ عَلَيْهِمْ ۚ إِنَّ فِي ذَٰلِكَ لَرَحْمَةً وَذِكْرَىٰ لِقَوْمٍ يُؤْمِنُونَ ٥١
And is it not enough for them that we have sent down to thee the Book which is rehearsed to them? Verily, in it is Mercy and a Reminder to those who believe.
قُلْ كَفَىٰ بِاللَّهِ بَيْنِي وَبَيْنَكُمْ شَهِيدًا ۖ يَعْلَمُ مَا فِي السَّمَاوَاتِ وَالْأَرْضِ ۗ وَالَّذِينَ آمَنُوا بِالْبَاطِلِ وَكَفَرُوا بِاللَّهِ أُولَٰئِكَ هُمُ الْخَاسِرُونَ ٥٢
Say: "Enough is Allah for a witness between me and you: He knows what is in the heavens and on earth. And it is those who believe in vanities and reject Allah, that will perish (in the end).
