Now The Braying Of The Asses
Here is a relevant passage in a Government of India publication (Pg. 305, Part II, Archeological Remains, Monuments and Museums, Archeological Survey of India, 1964). It says: "Humayun died in 1556, and his widow Hamida Banu Begam, also known as Haji Begam, commenced his tomb in 1569, fourteen years after his death. It is the first distinct example of proper Moghul style, which was inspired by Persian architecture. There need be no doubt that Humayun picked up the principles of Persian architecture during his exile, and he himself is likely to have planned the tomb, although there is no record to that effect (of course! - The Publisher.). Mirak Mirza Ghiyath, a Persian, was the architect employed by Haji Begam for this tomb."
(The amazing thing is that Humayun, the great accomplished architect in Indo-Saracenic architecture had not a single other work of art built by him before or after his death, under the direction of a Haji or a Paji Begam! - The Publisher.)
