While his hold over his own territory was thus weakened through the claims of a treacherous brother and the open attempts of the Afghāns, Humāyūn was forced to take notice of affairs outside. Suspecting the loyalty of Muhammad Zamān Mīrzā, who was not only his brother-in-law but was also descended like himself from Tīmūr, and had been appointed by Bābur governor of Bihār, he removed him from office in 1533 and placed him in confinement at Bayāna. Muhammad Zamān escaped and offered his services to Bahādur Shāh, king of Gujarāt, while a cousin named Muhammad Sultān and his sons who had been plotting with him were seized and sentenced to be blinded. The peaceful relations which existed between Gujarāt and Āgra were broken by the refusal of Bahādur Shāh to turn away the fugitives and by the terms of the letter sent in his name to Humāyūn.¹ His continued extension of authority towards central India and Rājputāna also aroused jealousy and some alarm. Humāyūn received an application for help from the Rānā of Chitor who was in danger of being crushed by his ambitious neighbour, and although Humāyūn's religious principles would not allow him to aid an unbeliever against an enemy of his own faith, he marched to Gwalior late in 1534 and called on Bahādur Shāh to stop his enterprise against the Rānā and again demanded the fugitives. Despairing of help from Āgra the Rānā came to terms with Bahādur Shāh and Humāyūn hoped to be able to attend to his eastern possessions where Afghān intrigue was most dangerous.
