Surah Yusuf, Verse 3
نَحْنُ نَقُصُّ عَلَيْكَ أَحْسَنَ ٱلْقَصَصِ بِمَآ أَوْحَيْنَآ إِلَيْكَ هَٰذَا ٱلْقُرْءَانَ وَإِن كُنتَ مِن قَبْلِهِۦ لَمِنَ ٱلْغَٰفِلِينَ
Translation — Sahih International
We relate to you, [O Muhammad], the best of stories in what We have revealed to you of this Qur'an although you were, before it, among the unaware.
