Muhammad Tahir (1628 – 1671) known by his title Inayat Khan, was an Indian historian during the Mughal Empire.

In his work the Shahjahannama, he chronicled the life of Mughal emperor Shah Jahan.

Inayat Khan was born in 1628, the same year that Mughal emperor Shah Jahan came to the throne.

In 1635, the seventh year of his life, he received as he informs us, "a suitable mansab".

In the reign of Shah Jahan, he was at one time ruler of Kabul, and afterwards of Kashmir, during which latter government he effected the conquest of Tibet.
