“There has been no Prophet in the history of the world who has not imparted teachings of prayer. It is prayer which forges a bond between man’s servitude (ubudiyyat) and divine providence (rububiyyat). It is difficult to tread this path, but one who does will find that prayer is a means by which all these difficulties become easy and painless. […] When an individual prays to God incessantly, they become a whole new person altogether; their spiritual impurities are cleansed and they are blessed with a kind of pleasure and tranquillity; after they are freed from all forms of prejudice and ostentation, they patiently endure all the hardships which arise on the path of God. They endure for the sake of God all those hardships which others do not and cannot bear, and they do so only to attain the pleasure of God Almighty. It is then that God Almighty, who is the Gracious and Merciful Lord, and the Epitome of compassion, turns His sight towards such a person and removes all of their troubles and impurities, and grants them bliss.”
