AJĀIB SIṄGH (d. 1705), one of the martyrs of Chamkaur, was the son of Bhāī Manī Rām, a Rājpūt Sikh of the time of Gurū Tegh Bahādur and Gurū Gobind Siṅgh. Manī Rām had presented five of his sons including Ajāib Siṅgh to Gurū Gobind Siṅgh at Anandpur where they took amrit or baptism of the double-edged sword on the historic day of the birth of the Khālsā on 30 March 1699. Ajāib Siṅgh thereafter remained in attendance upon the Gurū. He fell fighting at Chamkaur on 7 December 1705.
