"That city is known as their site of pilgrimage, a place which was Madina or free from intoxication. Having a form of a ghost (Bhuta), the expert illusionist Mahamada (Muhammad) appeared at night in front of king Bhojaraja and said: O king, your religion is of course known as the best religion among all. Still I am going to establish a terrible and demoniac religion by the order of the Lord . The symptoms of my followers will be that they first of all will cut their genitals, have no shikha, but having beard, be wicked, make noise loudly and eat everything. They should eat animals without performing any rituals. This is my opinion. They will perform purificatory act with the musala or a pestle as you purify your things with kusha. Therefore, they will be known as musalman, the corrupters of religion. Thus the demoniac religion will be founded by me. After having heard all this the king came back to his palace and that ghost (Muhammad) went back to his place. .... The musalman people were kept on the other side of the river Sindhu."
