"When one of you falls ill, he calls for the physician and pays him. When someone has a need from a ruler, he bribes the gatekeeper and gives him. However, if one of you is struck by an overwhelming concern and turns to Allah (swt), the Exalted, purifies himself (performs ablution), gives charity (whether small or large), then enters the mosque, prays two units (rak'ahs) of prayer, praises and glorifies Allah (swt), and invokes blessings upon the Prophet and his family (as), then says: 'O’ Allah (swt), if You cure me of my illness, or return me safely from my journey, or protect me from what I fear of such and such (mentioning the specific concern),' Allah (swt) would grant him that. This is the binding oath, and it is what Allah (swt), the Blessed and Exalted, has made incumbent upon one as an expression of gratitude."
