Gurdwara Majnu Tilla Sahib is located at Khyber Pass on Ring Road in Delhi. It is believed that on the banks of river Yamuna, there lived in Delhi a Muslim Sufi Darvesh, who led the life of a penitent recluse. So lonely and God-intoxicated was he that he was nicknamed Majnu, the mad lover. When he met Guru Nanak, he felt that he was in the presence of a prophet, who had imparted to him a new revelation. He felt spiritually exalted and illumined and the ‘Light of God’ was revealed to him.
Guru Nanak had many Muslim disciples in Punjab but Majnu was his first Muslim disciple in Delhi, who not only became a staunch devotee but a great missionary, who converted his Khangah into a shrine of Guru Nanak, which continues to be known after his name as Majnu-ka-Tilla to this day.
It is also believed that Guru Gobind Singh stayed at the Majnu Tilla shrine when he visited Delhi. Also, when Guru Har Rai sent his son Ram Rai to explain the tenants of Sikhism to Aurangzeb, he stayed at the shrine.
