﴿ نَحْنُ نَقُصُّ عَلَيْكَ أَحْسَنَ ٱلْقَصَصِ بِمَآ أَوْحَيْنَآ إِلَيْكَ هَٰذَا ٱلْقُرْءَانَ وَإِن كُنتَ مِن قَبْلِهِۦ لَمِنَ ٱلْغَٰفِلِينَ ﴾

“In the measure that We reveal this Qur'an unto thee, [O Prophet,] We explain it to thee in the best possible way, seeing that ere this thou wert indeed among those who are unaware [of what revelation is].”

(We narrate unto thee (Muhammad)) We clarify to you (the best of narratives) the best story of the news of Joseph and his brothers (in that We have inspired in you) with which We inspired through Gabriel (this Qur'an) in this Qur'an, (though aforetime) before Gabriel brought down the Qur'an to you (thou wast of the heedless) in relation to the event of Joseph and his brothers.
