Aal-'Imran - 3:79

مَا كَانَ لِبَشَرٍ أَن يُؤْتِيَهُ اللّهُ الْكِتَابَ وَالْحُكْمَ وَالنُّبُوَّةَ ثُمَّ يَقُولَ لِلنَّاسِ كُونُواْ عِبَادًا لِّي مِن دُونِ اللّهِ وَلَـكِن كُونُواْ رَبَّانِيِّينَ بِمَا كُنتُمْ تُعَلِّمُونَ الْكِتَابَ وَبِمَا كُنتُمْ تَدْرُسُونَ
[3:79]
It is not meet for a mortal that Allah should give him the Book and the wisdom and prophethood, then he should say to men: Be my servants rather than Allah's; but rather (he would say): Be worshippers of the Lord because of your teaching the Book and your reading (it yourselves).
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."
It is not (possible) for any human being unto whom Allah had given the Scripture and wisdom and the prophethood that he should afterwards have said unto mankind: Be slaves of me instead of Allah; but (what he said was): Be ye faithful servants of the Lord by virtue of your constant teaching of the Scripture and of your constant study thereof.
