Bhai Gurdas ji Vaar : Baba at Mecca Pauris: 32-34
Baba phiri Makkey gia neel bastatr Dharey banwari.
Aasa hathh Kitab Kachh kuja bang mussala dhari.
Ja Baba suta raat nounn vali maharabey paiye pasari.
Jivan maari latt di kehara suta kuffar kuffari.
Tangon Pakkaur ghasitia phiria Makka kalla dikhari.
Hoey hairan kareni Juhari.
Puchhan Pholi kitab nounn Hindu vada ke Musalmanoi.
Baba Aakhey hajian subh amlan bajhau dono roi.
Hindu Musalmaan dui dargah andari lahani na dhoi.
Karani bakhili aapi vichi Ram Rahim Kuthai Khaloi.
Rahey Saitani dunia goi.
In these pauris Bhai Gurdas ji describes the visit of Baba Nanak (Guru Nanak Sahib Ji) to Mecca(during Guruji's 4th udasi/journey to the west). Donning blue clothes, holding a stick in one hand, book under the arm pit and carrying his prayer mat and a lota (jug) Baba reaches Mecca and relates the well known anecdote about Guru Nanak Dev ji keeping his feet towards the Mehrab at night.
Hearing that a strange man had crept into their company, people gathered round him and asked to open and search in his book(pothi) and tell them as to who is better, Hindu or Muslim. Guru ji replied, "Without good deeds, both will come to grief. Only by being a Hindu or a Muslim one can not get accepted in the court of the Lord." As the colour of safflower is impermanent and is washed away in water, likewise the colours of religiosity are also temporary. (Followers of both the religions) In their expositions, denounce Ram and Rahim. The whole of the world is following the ways of Satan.
Then they asked, "Of what religion art thou?" Guru ji answered, "I am a mere man, made up of five elements, a play thing in the hands of God."
