The History of Shēr Shāh (Tārīkh-i Shērshāhī) 3.13.4

3.13.4

After the Emperor Humáyún had got possession of Chunár, he halted in Benares, and sent an envoy to Sher Khán, having it in view to get possession of the country of Bihár. Sher Khán knew he had this design, and said to the envoy, "I have captured the fort of Gaur, and have collected about me a very large force of Afgháns. If the Emperor will abandon all design upon Bengal, I will surrender Bihár to him, and make it over to whomsoever he will depute, and will agree to the same boundaries of Bengal as existed in Sultán Sikandar's time; and I will send all the ensigns of royalty—as the umbrella throne, etc.—to the Emperor, and will yearly send him ten lacs of rupees from Bengal. But let the Emperor return towards Ágra." The envoy came back to Humáyún, and reported what Sher Khán had said. The Emperor, on hearing about Bihár, became exceedingly glad, and agreed to what Sher Khán proposed, and gave a horse, and a peculiarly splendid khil'at to the envoy for delivery to Sher Sháh; and directed him to say to Sher Sháh that his proposals were accepted, and that he should not delay to put them in execution. The vakíl came to Sher Sháh, and gave him the horse and dress, and told him what the Emperor had said. Sher Khán was much delighted, and said, "I will fulfil the terms agreed upon, and will pray day and night to Almighty God that while life lasts no hostility may befall between the Emperor and myself, for I am his dependent and servant."
