Allah Subhanahu Wa Ta'ala said:
وَقَا لَتِ امْرَاَ تُ فِرْعَوْنَ قُرَّتُ عَيْنٍ لِّيْ وَلَكَ ۗ لَا تَقْتُلُوْهُ ۖ عَسٰۤى اَنْ يَّـنْفَعَنَاۤ اَوْ نَـتَّخِذَهٗ وَلَدًا وَّهُمْ لَا يَشْعُرُوْنَ
"And the wife of Pharaoh said, "[He will be] a comfort of the eye for me and for you. Do not kill him; perhaps he may benefit us, or we may adopt him as a son." And they perceived not."
(QS. Al-Qasas 28: Verse 9)
