The turban has been an important part of the Sikh religion since the time of the First Guru. Guru Angad Dev honoured Guru Amar Das ji with a special turban when he was declared the next Guru. At the time when Guru Ram Das passed away, Guru Arjan Dev was honoured with the turban of Guruship. Marne di pag Pirthiye badhi. Guriyaee pag Arjan Ladhi[1]
Guru Gobind Singh, the last human Sikh Guru, wrote:
Kangha dono vaqt kar, paag chune kar bandhai. ("Comb your hair twice a day and tie your turban carefully, turn by turn.")
Bhai Rattan Singh Bhangu, one of the earliest Sikh historians, wrote in Sri Gur Panth Parkash:[2]
Doi vele utth bandhyo dastare, pahar aatth rakhyo shastar sambhare
Kesan ki kijo pritpal, nah(i) ustran se katyo vaal
Tie your turban twice a day and wear shaster (weapons to protect dharma), and keep them with care, 24 hours a day. Take good care of your hair. Do not cut or damage your hair.

There are many Punjabi idioms and proverbs that describe how important is a turban in one's life. Bhai Gurdas writes:
Tthande khuhu naike pag visar(i) aya sir(i) nangai
Ghar vich ranna(n) kamlia(n) dhussi liti dekh(i) kudhange
("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.")
