Surat Yūsuf - سورة يوسف

نَحْنُ نَقُصُّ عَلَيْكَ أَحْسَنَ الْقَصَصِ بِمَا أَوْحَيْنَا إِلَيْكَ هَٰذَا الْقُرْآنَ وَإِن كُنتَ مِن قَبْلِهِ لَمِنَ الْغَافِلِينَ

Muhsin Khan: We relate unto you (Muhammad SAW) the best of stories through Our Revelations unto you, of this Quran. And before this (i.e. before the coming of Divine Inspiration to you), you were among those who knew nothing about it (the Quran).
