The rayeen of the Ghaggar valley say they were Rajputs living on the Panjnad near Multan who were ejected some four centuries ago by Saiyad Jalal-ul-din of Uch. They are the descendants of those Arab tribes who arrived with Umayyad general Muhammad Bin Qasim. They spread all over the lower ghagra valley from 1759to 1783 A. D. in the region of Behlol Lohdhi. But latter having conflicts with Hindu Bhattis they dispersed, and many of the Arains emigrated across the Ganges and settled near Bareli and Rampur.
