Baba Sain Mir Mohammed Sahib (c. 1550 – 22 August 1635), popularly known as Mian Mir or Miyan Mir, was a famous Sufi Muslim saint who resided in Lahore, specifically in the town of Dharampura (in present-day Pakistan). He was a direct descendant of Caliph Umar ibn al-Khattab. He belonged to the Qadiri order of Sufism. He is famous for being a spiritual instructor of Dara Shikoh, the eldest son of Mughal emperor Shah Jahan. He is identified as the founder of the Mian Khel branch of the Qadiri order. His younger sister Bibi Jamal Khatun was a disciple of his and a notable Sufi saint in her own right.
Mian Mir was a friend of God-loving people and he would shun worldly, selfish men, greedy Emirs and ambitious Nawabs who ran after faqirs to get their blessings. To stop such people from coming to see him, Mian Mir posted his mureeds (disciples) at the gate of his house.

According to Sikh tradition, the Sikh guru GuruArjan Dev Ji met Mian Mir during their stay in Lahore. This tradition does not appear in the early Sikh literature, and is first mentioned in the 18th and 19th century chronicles. However, it may be possible that this tradition is historically true, and may have been suppressed during the earlier period because of Sikhs' conflicts with the Muslim Mughalsand Afghans.
According to Tawarikh-i-Punjab (1848), written by Ghulam Muhayy-ud-Din alias Bute Shah, Mian Mir laid the foundation of the Sikh shrine Harmandir Sahib (Golden Temple), at the request of Guru Arjan Dev.[7] Although the earliest Sikh records state that the foundation stone was laid by Guru Arjun himself, the later Sikh records mention the legend that appears in Tawarikh-i-Punjab. The legend is repeated in several European sources, beginning with The Punjab Notes and Queries.[8] Even the Report Sri Darbar Sahib (1929), published by the Harmandir Sahib temple authorities, have endorsed this account.
However, this legend is unsubstantiated by historical evidence. Sakinat al-aulia, a 17th century biography of Mian Mir compiled by Dara Shikoh, does not mention this account. It appears only in the later accounts, and may have been invented to strengthen the Sikh-Muslim relationship.[6]
After having lived a long life of piety and virtuosity, Mian Mir died on 22 August 1635 (7 Rabi' al-awwal, 1045 according to the Islamic Calendar). He was eighty-eight years old.
His funeral oration was read by Mughal prince Dara Shikoh, who was a highly devoted disciple of the Saint. There is a hospital named after him in his hometown Lahore, called Mian Mir Hospital.
He was buried at a place which was about a mile from Lahore near Alamganj, that is at the south-east of the city. Mian Mir's spiritual successor was Mullah Shah Badakhshi. Mian Mir's Mazar(Mausoleum) still attracts hundreds of devotees each day and he is revered by many Sikhs as well as Muslims. The tomb's architecture still remains quite intact to this day. His death anniversary ('Urs' in Urdu language) is observed there by his devotees every year.
