Surah Al-Qasas (The Stories), Verse 9

وَقَالَتِ امْرَاَتُ فِرْعَوْنَ قُرَّتُ عَیْنٍ لِّیْ وَلَكَ لَا تَقْتُلُوْهُ عَسٰۤی اَنْ یَّنْفَعَنَاۤ اَوْ نَتَّخِذَهٗ وَلَدًا وَّهُمْ لَا یَشْعُرُوْنَ ۟

Wa qaalatim ra atu Fir'awna qurratu 'aynil lee wa lak; laa taqtuloohu 'asaaa aiyanfa'anaa aw nattakhizahoo waladanw wa hum laa yash'uroon

“The wife of Pharaoh said: "(Here is) A joy of the eye, for me and for thee: slay him not. It may be that he will be use to us, or we may adopt him as a son." And they perceived not (what they were doing)!”
