Akbur, after this conquest, made a pilgrimage to Khwaja Moyin-ood-Deen Chishty at Ajmere and returned to Agra; from whence he proceeded to visit the venerable Sheikh Sulim Chishty, in the village of Seekry. As all the king's children had hitherto died, he solicited the Sheikh's prayers, who consoled him, by assuring him he would soon have a son, who would live to a good old age. Shortly after, his favourite sooltana, being then pregnant, on Wednesday the 17th of Rubbee-ool-Awul, in the year 997 was delivered of a son, who was called Sulim.
