Hazrat Shahr bin Hawshab narrates that I asked Umm al-Mu’minin Hazrat Umm Salamah: O Umm al-Mu’minin! When the Messenger of Allah (peace and blessings be upon him) was with you, which supplication did he make most frequently? She replied: He (peace and blessings be upon him) would often supplicate: O Turner of hearts! Make my heart steadfast upon Your religion. Then he (peace and blessings be upon him) said: O Umm Salamah! Every person’s heart is between two fingers of Allah; Allah keeps firm on the religion whom He wills, and turns away the heart of whom He wills.
