After this with kingly energy and determination, he girded up his loins for a war of religion, and invaded Hindustan, and carried away many prisoners… - Sabuktigin

When this intelligence reached the Amír, he considered it false, as being opposed to the usual habits of Jaipál; but after repeated accounts to the same effect were brought, when the curtain which obscured the truth was withdrawn, and he knew that God has set his seal upon Jaipál's heart, so that he might obtain the reward of his evil deeds, and placed a veil between it and rectitude, so that he might obtain punishment for his wickedness and infedelity. The Sultan therefore sharpened the sword of intention in order to make an incursion upon his kingdom, and cleanse it from impurity and from his rejection of Islam. So he departed with his valiant servants and allies, relying upon the one God, and trusting in the fulfilment of the promise of the victory; and he went on till he arrived with his troops in the country of Hind, and he killed everyone who, on the part of Jaipál, came out to oppose him.

After this expedition he made frequent expeditions into Hind, in the prosecution of holy wars, and there he conquered forts upon lofty hills, in order to seize the treasures they contained, and expel their garrisons. He took all the properties they contained into his own possession, and captures cities in Hind, which had up to that time had been tenanted only by infidels, and not trodden by the camels and horses of the Musalmáns.

When the Amír heard these words, and knew what Jaipál would do in his despair, he thought the religion and the views of the faithful would best be consulted by peace, and the acquisition of tribute. So the Amír Mahmúd agreed with Subuktigín as to the propriety of withdrawing his hand of vengeance, on the condition of receiving at that time 1,000,000 dirhams of royal stamp, and some cities and forts in the middle of his country. Jaipál was to deliver these forts to the officers nominated by the Amír, and was to send hostages from among his relatives and friends to remain with the Amír until these conditions of cession were fulfilled. The Amír sent two deputies with Jaipal to see that he did not swerve from his engagements, and they were accompanied by confidential officers who were to receive charge of the ceded places.
