Al-Qasas - 28:11

وَقَالَتْ لِأُخْتِهِ قُصِّيهِ فَبَصُرَتْ بِهِ عَن جُنُبٍ وَهُمْ لَا يَشْعُرُونَ
[28:11]
And she said to his sister: Follow him up. So she watched him from a distance while they did not perceive,
And she said to the sister of (Moses), "Follow him" so she (the sister) watched him in the character of a stranger. And they knew not.
And she said unto his sister: Trace him. So she observed him from afar, and they perceived not.
