Shaikh Abdul Qadir Jilani () addresses the Ulama saying, "O Ulama who are qualifying from Deeni institutions! Before you take the responsibility of preaching from the mimbar, go and sit in the company of an Allah-Wala for 6 months to one year". Go and serve them with humility so that the Maula of the books you studied may become manifest in your heart. Then your heart will become the possessor of Noor (Divine Light) and thereafter you will be a different person altogether. You will spread the sweet fragrance of Dard-e-Dil ¹ wherever you go; whether it is by the riverside, in the jungles, or by the mountainsides, even in the condition where your clothes are tattered out of poverty. The people of wealth and luxury will salute you and search for you saying, "Where is the one who was dispensing the tonic of Dard-e-Dil? Where has he set up his shop?" I have composed a couplet about this:

In the lap of my poverty, the crown of Caesar is hidden,
A small amount of Dard-e-Dil is no less than attaining both worlds.
