29:48
وَمَا كُنْتَ تَتْلُوا مِنْ قَبْلِهٖ مِنْ كِتَابٍ وَلَا تَخُطُّهُ بِیَمٖینِكَ اِذًا لَارْتَابَ الْمُبْطِلُونَ
Wama kunta tatloo min qablihi min kitabin wala takhuttuhu biyameenika ithan lairtaba almubtiloona
Translations
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
Saheeh International
And thou (O Muhammad) wast not a reader of any scripture before it, nor didst thou write it with thy right hand, for then might those have doubted, who follow falsehood
