Muhammad Sultan was ordered to march back through Ankara to re-join the main army at Kayseri.
However, during this journey the prince, already suffering from injuries sustained during the recent battle, fell seriously ill.
He died on 12 March 1403, near the city of Afyonkarahisar.
Timur bitterly grieved his grandson's passing and ordered the entire army wear dark clothing in mourning.
A two hundred horse procession accompanied Muhammad Sultan's body to the fortress of Avnik.
From there, he was taken to be temporarily buried in the mazar of Qedar, near the city of Soltaniyeh.

On the anniversary of his death the following year, Muhammad Sultan's remains, accompanied by his mother, were taken for reburial in Samarqand.
He was interred in a vault that bore his name, the Khangah-i Muhammad Sultan, part of an existing complex of religious buildings previously erected by the prince.
Upon his own death in 1405, Timur was buried there alongside his grandson.
Finally, both bodies were moved once more to their present resting-place in the Gur-i-Amir, likely around 1409 by Timur's successor Shah Rukh.
The tomb, originally intended for Muhammad Sultan alone, became the Timurid dynastic mausoleum.
