﴿ وَقَالَتِ ٱمْرَأَتُ فِرْعَوْنَ قُرَّتُ عَيْنٍۢ لِّى وَلَكَ ۖ لَا تَقْتُلُوهُ عَسَىٰٓ أَن يَنفَعَنَآ أَوْ نَتَّخِذَهُۥ وَلَدًۭا وَهُمْ لَا يَشْعُرُونَ ﴾

“Now the wife of Pharaoh said: “A joy to the eye [could this child be] for me and thee! Slay him not: he may well be of use to us, or we may adopt him as a son!” And they had no presentiment [of what he was to become].”

And Pharaoh’s wife said after he and his aids had resolved to slay him he is ‘A joyous sight for me and you. Do not slay him. Perhaps he will be of benefit to us or we will adopt him as a son’ and so they obeyed her wish. And they were not aware of the sequel to their affair with him.
