3:79
مَا كَانَ لِبَشَرٍ أَن يُؤْتِيَهُ اللّهُ الْكِتَابَ وَالْحُكْمَ وَالنُّبُوَّةَ ثُمَّ يَقُولَ لِلنَّاسِ كُونُواْ عِبَاداً لِّي مِن دُونِ اللّهِ وَلَـكِن كُونُواْ رَبَّانِيِّينَ بِمَا كُنتُمْ تُعَلِّمُونَ الْكِتَابَ وَبِمَا كُنتُمْ تَدْرُسُونَ
It is not (possible) that a man, to whom is given the Book, and Wisdom, and the prophetic office, should say to people: "Be ye my worshippers rather than Allah's": on the contrary (He would say) "Be ye worshippers of Him Who is truly the Cherisher of all: For ye have taught the Book and ye have studied it earnestly."
6:105
وَكَذَلِكَ نُصَرِّفُ الآيَاتِ وَلِيَقُولُواْ دَرَسْتَ وَلِنُبَيِّنَهُ لِقَوْمٍ يَعْلَمُونَ
Thus do we explain the signs by various (symbols): that they may say, "Thou hast taught (us) diligently," and that We may make the matter clear to those who know.
6:156
أَن تَقُولُواْ إِنَّمَا أُنزِلَ الْكِتَابُ عَلَى طَآئِفَتَيْنِ مِن قَبْلِنَا وَإِن كُنَّا عَن دِرَاسَتِهِمْ لَغَافِلِينَ
Lest ye should say: "The Book was sent down to two Peoples before us, and for our part, we remained unacquainted with all that they learned by assiduous study:"
34:44
وَمَا آتَيْنَاهُم مِّن كُتُبٍ يَدْرُسُونَهَا وَمَا أَرْسَلْنَا إِلَيْهِمْ قَبْلَكَ مِن نَّذِيرٍ
But We had not given them Books which they could study, nor sent messengers to them before thee as Warners.
