Shaykh Haji Imdadullah mohajir Makki gave khilafat to Mawlana Rasheed Ahmad Gangohi (Allah have mercy on them) after eight days and told him: ‘Moulvi Rasheed Ahmed sahib whatever favour (nimat) Allah has bestowed upon me, He has also bestowed upon you. It will be your duty to go develop that nimat and work on it.’

Mawlana Gangohi used to say: ‘I was very surprised. I could not understand what nimat he was referring to, which had been granted to him and also to me. I only managed to understand and realise what it was fifteen years later.’

Shaykh Dr. Abdul Hayy Arifi (Allah have mercy on him) explicitly told his khulafa (Mufti Rafi Usmani db, Mufti Taqi Usmani db, Mufti Sehban Mehmood ra and others) to wait for spiritual puberty & maturity (of wich they will become undoubtedly aware of themselves) before taking the responsibility of being a Shaykh in spite of having recieved permission (ijazet) to guide others.
