Bhai Mati Das (d. 24 November1675) (Punjabi: ਭਾਈ ਮਤੀ ਦਾਸ) is one of the great martyrs in Sikhhistory. He along with his younger brother Bhai Sati Das and Bhai Dyal Das, all disciples of the ninth Sikh Guru,Guru Teg Bahadur, were executed along with Guruji at theKotwali (police-station) near the Sunehri Masjid in the Chandni Chowk area of Old Delhi, under the express orders of emperorAurangzeb.
Born to a Brahmin[1][2] family of the Chhibber clan, Bhai Mati Das belonged to the village of Karyala, a stronghold of the Chhibbers, in the Jhelum District in Punjab (Pakistan), about ten kilometres from Chakwal on the road to the Katas RajTemple Complex. The village stands on the top of the Surla hills. This part of the country is known as Dhani meaning rich. A few kilometres away are the Salt Mines and coal mines ofDandot. The Katas lake is beautiful.
His grandfather, Bhai Praga, had embraced the Sikh faith in the time of Guru Hargobind and had taken part in battles with theMughal forces. His uncle Dargah Mall served Guru Har Rai andGuru Har Krishan as Diwan or manager of the household. Bhai Mati Das and his brother, Bhai Sati Das, assisted Dargah Mall in his work during Guru Tegh Bahadur's time. The former was himself appointed Diwan along with Dargah Mall who was by then considerably advanced in years.
Diwan Mati Das accompanied Guru Tegh Bahadur during his travels in the eastern parts in 1665-70. He was one of the companions of the Guru who were detained at Dhamtan in 1665 and then released from Delhi at the intervention of Kanvar Ram Singh, of Amber. In 1675, when the Guru set out from Anandpur for Delhi, Bhai Mati Das bravely faced certain death as he volunteered to accompany Guru Tegh Bahadur to Aurangzeb's Court to confront the Emperor over his threat of forcing the Pandits of Kashmir to convert to Islam or be killed. The Guru and his steadfast companions were arrested under imperial orders, and taken in chains to Delhi. Upon his refusal to forswear his faith, he was tortured to death. He was, on 24 November 1675, sawn in half, from his head - downwards.
