Nāsir-ud-dīn Qabācha's acknowledgement of his father-in-law, Aibak, as his sovereign aroused the resentment of Tāj-ud-dīn Yildiz, governor of Kirmān, who claimed the succession to Muhammad in Ghaznī and, in consequence, the sovereignty of the Punjab. He sent an army against Qabācha and drove him from Multān but was in turn attacked by Aibak, defeated, and driven back to Kirmān. Aibak, elated by his success, entered Ghaznī as a conqueror in 1208-09 and celebrated his victory with wine and revelry, while his troops robbed and ill-treated the citizens. They secretly informed Yildiz of the state of affairs and he suddenly marched on Ghaznī and so completely surprised Aibak that he fled to Lahore without striking a blow.
