﴿ قَالُوا۟ يَٰٓأَبَانَآ إِنَّا ذَهَبْنَا نَسْتَبِقُ وَتَرَكْنَا يُوسُفَ عِندَ مَتَٰعِنَا فَأَكَلَهُ ٱلذِّئْبُ ۖ وَمَآ أَنتَ بِمُؤْمِنٍۢ لَّنَا وَلَوْ كُنَّا صَٰدِقِينَ ﴾
“[and] said: "O our father! Behold, we went off racing with one another, and left Joseph behind with our things; and thereupon the wolf devoured him! But [we know that] thou wouldst not believe us even though we speak the truth" -”
