ما هو الدعاء الذي كان يدعو به سيدنا محمد صلى الله عليه وسلم للثبات على الطريق المستقيم والتقيد بالدين؟

A Muslim should be in a state between fear and hope, by fulfilling commands and abandoning prohibitions, then turning to Allah with supplication, hoping for steadfastness on the straight path. The Prophet, peace and blessings be upon him, said: "There is no heart but it is between two of the Fingers of the Most Merciful; if He wills, He keeps it straight, and if He wills, He deviates it." And Allah, the Almighty, said: {Allah keeps firm those who believe, with the steadfast word, in the worldly life and in the Hereafter. And Allah lets astray the wrongdoers. And Allah does what He wills.} And among the supplications of the Prophet, peace and blessings be upon him, was: "O Turner of hearts, keep my heart firm upon Your religion." It is advisable to refer to the authentic books of supplications.
