Yusuf • BN-TAFSEER-IBN-E-KASEER
﴿ ٱرْجِعُوٓا۟ إِلَىٰٓ أَبِيكُمْ فَقُولُوا۟ يَٰٓأَبَانَآ إِنَّ ٱبْنَكَ سَرَقَ وَمَا شَهِدْنَآ إِلَّا بِمَا عَلِمْنَا وَمَا كُنَّا لِلْغَيْبِ حَٰفِظِينَ ﴾
“[And as for you others,] return to your father and say: `O our father! Behold, thy son has stolen-but we [can] bear witness to no more than what has become known to us; and [although we gave you our pledge,] we could not guard against something that [lay hidden in the future and, hence,] was beyond the reach of our perception.”
