On his way back to Āgra from Mālwā, Sher Shāh persuaded the commandant of Ranthambhor to surrender that fortress to him, and after his return he remained for a year in Āgra, engaged in reorganising the administration of his empire, in the laying out of roads, and the erection of public buildings. Sher Shāh then paid a visit of inspection to Bihār and Bengal, in the course of which he suffered so severely from malaria as to believe himself to be at the point of death, and to vow that if God spared his life and restored him to health he would punish Pūran Mal for his offences against Islām.¹
