“How many years have we been coming to London regularly to be with you? For the last thirteen or fourteen years we have been coming here. Tell me, have we called you to anything but the Truth? If we were calling people to ourselves or to some sensations for their egos, many people might come – even more perhaps than now come – but they would not be consistent or perseverant: there would be a high turnover. But no, the same people who joined us then, twelve or fourteen years ago are still with us, and more are coming all the time. They too are staying with us. The ability of a shaykh to help his followers attain stability and a permanent way a sign of a true follower of the holy Prophet ﷺ.”
