"Kitab Zan-ul-Akhbar, the earliest source, gives the following account : ‘From that place Mahmud turned back, and the reason was that Param Deo, who was the king of the Hindus, was in the way, and the Amir Mahmud feared lest this great victory might be spoiled. He did not come back by the direct way, but took a guide and marching by the way of Mansura and the bank of the Sihun, went towards Multan. His soldiers suffered heavily on the way, both from the dryness of the desert and from the Jatts of Sind. Many animals and a large number of men of the Muslim army perished on the way, and most of the beasts of burden died, till at last they reached Multan.’’ (Kitab Zan-ul-Akhbar, , 86-7)"
