Why do women have to cover when they pray, even if they are at home and no male is present?
Hiajb is a symbol of a woman’s servitude to God (not to her husband as portrayed in the West). Thus, it is seen as her best dress code when she is standing before her Creator. We are recommended to wear our adornments when praying. ‘Adornment’ here is not to seduce but to be more humble and decent before God.
Men are also recommended to wear ‘Aba and turbans (which were outdoor dresses) in the old days, even if they pray in their bedroom. And God knows best.
