نَحْنُ نَقُصُّ عَلَيْكَ أَحْسَنَ الْقَصَصِ بِمَا أَوْحَيْنَا إِلَيْكَ هَـذَا الْقُرْآنَ وَإِن كُنتَ مِن قَبْلِهِ لَمِنَ الْغَافِلِينَ
[12:3]
We narrate to you the best of narratives, by Our revealing to you this Quran, though before this you were certainly one of those who did not know.
We do relate unto thee the most beautiful of stories, in that We reveal to thee this (portion of the) Qur'an: before this, thou too was among those who knew it not.
We narrate unto thee (Muhammad) the best of narratives in that We have inspired in thee this Qur'an, though aforetime thou wast of the heedless.
