Exiting our local metro station the other day I saw this sign posted above the entrance:
It translates: The hijab (Islamic head covering) is a religious obligation, just like prayer. Cover yourself before you are held accountable.
That sounds ominous, but it can read that the holding accountable is done by God. Still, in some countries there are groups of religious police. It is interesting to note this sign is posted without any reference to its author. Muslim Brotherhood? Salafi groups? Unknown.
Is it a warning, a reminder, or an encouragement? At the least it is a sign of the times.
