وَمَا كُنتَ تَتۡلُواْ مِن قَبۡلِهِۦ مِن كِتَٰبٖ وَلَا تَخُطُّهُۥ بِيَمِينِكَۖ إِذٗا لَّٱرۡتَابَ ٱلۡمُبۡطِلُونَ
Wa maa kunta tatloo min qablihee min kitaabinw wa laa takhuttubhoo bi yameenika izal lartaabal mubtiloon
English Translation
And you did not recite before it any scripture, nor did you inscribe one with your right hand. Otherwise the falsifiers would have had [cause for] doubt
