Hadhrat Hakim al-Ummat [Mawlana Ashraf ‘Ali Thanawi], may Allah shower him with mercy, relates that a person once came to Hadhrat Haji [Imdadullah] sahib, may Allah shower him with mercy, and asked to be taught a wazifah (litany) by which he would be blessed with seeing the Prophet, peace and blessings upon him, in his dreams. 

Hadhrat [Haji sahib] replied, 

“You have great ambitions. We are not even worthy of being blessed with the vision of the dome of the blessed Rawdha (the resting place of the Prophet (peace and blessings upon him)).”
