Return to your father and say, ‘O our father! Your son committed theft. We testify only to what we know. We could not guard against the unforeseen.19

A. Yusuf Ali:Translation:
"Turn you back to your father, and say, ´O our father!
behold! your son committed theft! we bear witness only
to what we know, and we could not well guard against
the unseen! 1754

Muhammad Asad:Translation:
[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; 83 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. 84
19 We did not know when we gave you our solemn oath that our brother was going to steal.
