Qutb al-Din Muhammad
Qutb al-Din Muhammad (died 1346) was the Mihrabanid malik of Sistan from December 1330, raised to power after his uncle Nusrat al-Din Muhammad died. A deeply religious man, he patronized Sistan's religious figures, fed travelers and the poor, and distributed its fortresses among his family.
The collapse of Ilkhanid rule spared Sistan most of the wars ravaging Persia, though a Kartid army invaded in 1333 at the bidding of his opponents before withdrawing. Qutb al-Din died of plague in 1346, and his son Taj al-Din succeeded him.
