He was one of the chief men of Shiraz. My honoured father, on account of his former services, paid him great honour and reverence. I made Raja Man Singh — who was one of the greatest and most trusted noblemen of my father, and had obtained alliances with this illustrious family, inasmuch as his aunt had been in my father's house (i.e. was his wife), and I had married his sister, and Khusrau and his sister Sultanu-n-nisa Begam, the latter of whom is my eldest child, were born of her — as before, ruler of the province of Bengal. Though as in consequence of certain of his acts he had no expectation of this favour towards himself, I dignified him with a charqab (vest without sleeves) as a robe of honour, a jewelled sword, and one of my own horses, and sent him off to his province, which is a place of (or can keep up) 50,000 horse. His father was Raja Bhagwan Das. His grandfather, Raja Bihari Mal, was the first of the Kachwaha Rajputs to have the honour of entering my father's service, and he excelled his tribe in truth and sincerity of friendship, and in the quality of valour. After my accession, when all the nobles with their retinues presented themselves at my palace, it came into my mind that I should send this body of retainers under my son, Sultan Parwiz, to make a holy war against the Rana, who was one of evil deeds, and a foul infidel of the country of Hindustan, and in my father's time had had troops sent constantly against him, but had not been driven off.
