Yusuf's Brothers try to deceive Their Father

Allah narrates to us the deceit that Yusuf's brothers resorted to, after they threw him to the bottom of the well. They went back to their father, during the darkness of the night, crying and showing sorrow and grief for losing Yusuf. They started giving excuses to their father for what happened to Yusuf, falsely claiming that,

إِنَّا ذَهَبْنَا نَسْتَبِقُ

وَجَاءُوا عَلَىٰ قَمِيصِهِ بِدَمٍ كَذِبٍ ; (And they came with fake blood on his shirt) that is, the brothers of Sayyidna Yusuf (علیہ السلام) came back with his shirt they had smeared in fake blood so that they could make their father believe that he has been eaten up by a wolf.

But, Allah Ta’ ala had His way of exposing their lie. He made them neglect something else they should have done besides smearing the shirt with fake blood. Had they also torn the shirt, it would proved his being eaten up by a wolf. Here they were coming with an intact shirt smeared with the blood of a kid goat and trying to deceive their father. After seeing this shirt totally unscratched, Sayyidna Ya'qub (علیہ السلام) said: My sons, certainly wise was this wolf who ate Yusuf in a way that his shirt was not torn from anywhere.
