ĀLĪ SIṄGH (d. 1716), a native of the village of Salaūdī, near Sirhind, was in the service of Wazīr Khān, the Mughal faujdār of Sirhind. According to Ratan Siṅgh Bhaṅgū, Prāchīn Panth Prakāsh, Wazīr Khān, on learning of Bandā Siṅgh's advance from the South towards the Punjab under the orders of Gurū Gobind Siṅgh, called Ālī Siṅgh to his presence and taunted him with the remark that another Gurū of theirs had appeared and that he should join him and bring him to Sirhind to be despatched after the previous Gurū's sons. Ālī Siṅgh took his comment as an insult. Wazīr Khān put him into prison from where he escaped and joined Bandā Siṅgh's ranks. Ālī Siṅgh took part in battles fought at Samāṇā and Saḍhaurā. In the battle of Sirhind fought on 12 May 1710 at the nearby village of Chappar Chīṛī, he was one of the commanders of the Mālvā Sikhs. After the sack of Sirhind, he was appointed deputy governor of the town under Bāj Siṅgh. Ālī Siṅgh was captured in Lohgaṛh in 1710, while defending the fortress against the Mughal onslaught and after several years of imprisonment, was put to death in Delhi in June 1716 with Bandā Siṅgh Bahādur and his men seized in Gurdās-Naṅgal.
