Qutb al-Din Mohammad — was Qutlughanid ruler of Kerman and a nephew of Buraq Hajib, founder of dynasty.
However, his reign was very short as he was quickly replaced by his cousin Rukn al-Din on the order of Ögedei Khan.
He left for Mongolia through Shahdad-Zozan route and was ordered to join Mahmud Yalavach in China as soon as he arrived.
As the result, Rukn al-Din fled to his nephew Salghur shah - Atabeg of Yazd with his mother Uka Khatun in 1252, later getting into contact with Caliph al-Mustasim.
When Möngke heard of this treason thanks to a commander named Buqa, he authorised Qutb al-Din to execute his cousin.
