Unfortunately many of the writers are not in the way of right. This is very clear situation that after the period of Khalafitay Rashida all the conquest are not base on religion. but the rule of every period is that on that areas which are under the control of muslims are mustly affected by religion of islam. A group of muslims always present who give there best services for the preach of islam. so conquest of sindh was just only the need of time not preplane attack
