Quran 12:17

قَالُواْ يَـٰٓأَبَانَآ إِنَّا ذَهَبۡنَا نَسۡتَبِقُ وَتَرَڪۡنَا يُوسُفَ عِندَ مَتَـٰعِنَا فَأَڪَلَهُ ٱلذِّئۡبُ‌ۖ وَمَآ أَنتَ بِمُؤۡمِنٍ۬ لَّنَا وَلَوۡ ڪُنَّا صَـٰدِقِينَ ١٧

They said, "Our father, we went racing with each other, leaving Joseph with our equipment, and the wolf devoured him. You will never believe us, even if we were telling the truth."
