Hazrat Haji Imdadullah Sahab Makkah Migratory gave the following remedy for the spiritual disease of show (riya). If you suspect that an act of yours has some content of show then do not give it up for that will only confirm that it lacked purity of intent. Instead of giving up that act indulge in that excessively. Slowly it will turn into an habit. If you continue that further then it will enter into worship and obedience.
