Aslah Ali Khan, whose real name was Rai Kunwar, was a Gujjar of Panipat and a commander of Sabit Khan Bahadur, the amir and faujdar of the pargana of Sikandara and the sarkar of Kol (present-day Aligarh). He was known as a eunuch, but was, in fact, a hermaphrodite and had a flowing beard. There was no indication of lack of spirits in him, for none of the manly people had the strength and courage to face him in the open field, and many deeds were accomplished by his powerful hands. After Sabit Khan Bahadur's death in 1730, all his mahals (revenue divisions or estates) were allotted to Aslah Ali Khan.

In 1148 AH (1735/1736), Aslah Ali Khan is recorded to have fought a battle against Akbar Khan Bangash, son of Muhammad Khan Bangash of Farrukhabad, in which the latter the was slain.

In the Battle of Karnal, Aslah Ali Khan joined Amir-ul-Umara Khan Dauran with a body of his own men and was posted on the right, close to the naqqar-khana (drum house), as the commander of Emperor Muhammad Shah's bodyguards. He was among the high-ranking Mughal nobles and officers who died on the battlefield fighting against Nadir Shah's army.
