COMMENTARY on 12:29
Mustafa Khattab:

Translation:
O  Joseph! Forget about this. And you ˹O wife˺! Seek forgiveness for your sin.8 It certainly has been your fault.”
Commentary:
8   She was urged to seek forgiveness from her husband.

 

A. Yusuf Ali:

Translation:
"O Joseph, pass this over! (O wife), ask forgiveness for your sin, for truly you have been at fault!" 1676
Commentary:

1676  As was only fair, he apologised to Joseph and begged him to give no further thought to the injury [hat had been done to him, first by the love-snare of his wife, secondly, by the utterly false charge made against him, and thirdly, by the scene, which must have been painful to a man of such spotless character as Joseph. That was not enough. He must ask his wife humbly to beg J oseph's pardon for the wrong that she had done him. And he must further ask her to consider her unbecoming conduct in itself, apart from any wrong done to Joseph. (R).

 

Muhammad Asad:

Translation:
[But,] Joseph, let this pass! 26 And thou, [O wife,] ask forgiveness for thy sin-for, verily, thou hast been greatly at fault!"
Commentary:
26  Lit., "turn aside from this". According to almost all the commentators, the meaning is, "do not mention this to anyone", the implication being that the husband was prepared to forgive and forget.
