From the Holy Prophet's time to our own we should follow Jama't only, through which we have received Islam. Intellect may or may not agree, it should be accepted with eyes shut, for no order of this group reported from the Holy Prophet is such that it may have any conflict with reason or be contrary to it. However, the higher in grade this order is, the reason to understand it too should also be of the same order. Hence if our defective intellect cannot grasp something in it, we must not try to tamper with anything religious. One should try to understand it from learned experts of the subject; or there have been written hundreds of books on this topic in which all the statements of the predecessors have been reasoned out intellectually.
In short, the skirt of this group must not be let off under any circumstances, as otherwise there is fear of destruction.
