قَالُوا۟ يَٰٓأَبَانَآ إِنَّا ذَهَبْنَا نَسْتَبِقُ وَتَرَكْنَا يُوسُفَ عِندَ مَتَٰعِنَا فَأَكَلَهُ ٱلذِّئْبُ ۖ وَمَآ أَنتَ بِمُؤْمِنٍۢ لَّنَا وَلَوْ كُنَّا صَٰدِقِينَ
Saying: O our father! We went racing one with another, and left Joseph by our things, and the wolf devoured him, and thou believest not our saying even when we speak the truth.
