It is believed that in 325 BCE Alexander the Great founded a city called Alexandria on the Indus at the site of the last confluence of Punjab rivers with the Indus.Nevertheless, some historians believe that Uch predates the advent of Bikramjit when Jains and Buddhists ruled over the area, and that Mithankot or Chacharan Sharif was the true settlement of Alexandria.
Alexander Cunningham writes that in describing the geography of Multan it is necessary to bear in mind the great changes that have taken place in the courses of all the large rivers that flow through the province.
In the time of Timur and Akbar the junction of the Chenab and Indus took place opposite Uchh, 60 miles above the present confluence at Mithankot.
Muhammad Aqil's shrine was at Kot Mithan, but, when Ranjit Singh conquered the Derajat, Khawaja Khuda Bakhsh, Mahbub Ilahi, his descendant, settled at Chacharan Sharif, which may now be regarded as the head- quarter of the Bahawalpur State religion.
Muhammad Aqil displayed many miracles and in his old age, owing to his spiritual enlightenment, had no shadow; so he used to come out of his house on dark nights only, in order to conceal his sanctity.
