التاريخ اليميني 4: Receipt by Mahmud of a Khila't from the Khalifa.

4

Kadir bi-llah Amiru-l-muminin, the Khalifa of Baghdad, sent a Khila't, such as had never before been heard of, for the use of Sultan Saifu-d daula, and he entitled Mahmud in his imperial rescript, "Yaminu-d daula Aminu-l millat, the friend of the Amiru-l muminin," which had not yet been bestowed upon any prince, either far or near, notwithstanding their intense desire to receive such an honour. The Sultan sat on his throne and robed himself in his new Khila't, professing his allegiance to the successor of the prophet of God. The Amirs of Khurasan stood before him in order, with respectful demeanour, and did not take their seats till they were directed. He then bestowed upon the nobles, his slaves, his confidential servants, and his chief friends, valuable robes and choice presents, beyond all calculation, * * * and vowed that every year he would undertake a holy war against Hind.
