Barani refers many times to the sources of information, he did not consult his contemporary works. This resulted in the sketchy description of Ala-ud-Din Khalji’s wars in Chittor, Ranthambhor and Malwa and the Deccan campaigns of Malik Kafur. The later medieval historians, Nizam-ud-Din Ahmad, Badaoni, Ferishta and Haji-ud-Dabir depended upon the Tarikh-i-Firuz Shahi for their account of history of the period covered in this work. Abdul Haq Dehlvi in his Akhbar-ul-Akhyar depended upon the work for the biographical sketches of Nizam-ud-Din Auliya and the other Sufi saints.
