my reply is to the brother who questioned how thats poosible to receite darood in such a  large quantity, i have seen, met hazarat g and other senior brothers many times they all were capable of receiting darood sharif much more faster and ACCURATELY, hazarat g himself was used to receite darood in very large quantity and this is hazrat g special faiz. so this is living karat of hazarat g and it cannot be understood just using your mind.
