A senior associate of Shaykh Wasiullah Allahabadi (Allah have mercy on them) descibing the Shaykhs methodolgy in this regards said,

 ‘The Shaykh did a thorough study of the state of the common and elite (around him). Then according to it he started to advice them in the light of Quran and Sunna. The success of this method is clearly evident in all the sectors of population (that visited him).

It was not that the people required instructions in the basics and in front of them the superior states of the Holy Companions (Allah be pleased with them) were elaborated and no discussion was made about the spiritual diseases afflicting the audience. This would have confused them about their own spiritual state. (That is, by being ignorant of their own poor diseased state and falsely comapring it to the  (healthy) believers state.) Then for obvious reasons how could they strive for islah ?’
