It is narrated from Sayyida Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) used to frequently supplicate: "O Turner of the hearts, keep my heart firm upon Your religion." I said: O Messenger of Allah, you also frequently make this supplication. The Prophet (peace and blessings be upon him) said: Indeed, the heart of a person is between two fingers from among the fingers of Allah Almighty; if He wills, He turns it aside, and if He wills, He keeps it straight.
