Muslim men and women in many countries still wear turban. It is said that the Egyptians removed their turban during mourning. Even in Punjab, removing a turban from a person's head was, at one time, considered a sign of mourning. Bhai Gurdas, a Sikh savant, who was contemporary of the third, fourth, fifth and sixth Nanak, writes in his Vars:

Tthande khuhu naike pag visar(i) aya sir(i) nangai |
Ghar vich ranna(n) kamlia(n) dhussi liti dekh(i) kudhange |
(Vara(n) Bhai Gurdas, Var 32, pauri 19)
TMFy KUhU nhwieky p`g ivsrI, AwieAw isrI nMgy,
Gr ivc rMnW kmlIAW DusI ilqI dyKI kuDMgy]
(vwrW BweI gurdws, vwr 32, pOVI 19)
Translation:
A person, after taking a bath at the well during winter time, forgot his turban at the well and came home bareheaded. When the women saw him at home without a turban, they thought someone had died and they started to cry.

There are many Punjabi idioms and proverbs that describe how important is a turban in one's life.
