Muslim Girl's Society

In Chapter 24 known as an-Nur (the Light), in verse 30, Allah commands Prophet Muhammad as follows:

قُلْ لِلْمُؤْمِنِيْنَ يَغُضُّوْا مِنْ أَبْصَارِهِمْ وَ يَحْفَظُوْا فُرُوْجَهُمْ, ذَلِكَ أَزْكَى لَهُمْ.
“Say to the believing men that: they should cast down their glances and guard their private parts (by being chaste). This is better for them.”

This is a command to Muslim men that they should not lustfully look at women (other than their own wives); and in order to prevent any possibility of temptation, they are required to cast their glances downwards. This is known as “hijab of the eyes”.
