Prayer for a resolute heart

Hazrat Umm-e-Salamah^ra was asked what the most oft-repeated prayer of the Holy Prophet^sa was. She replied and said the following prayer:

يَا مُقَلِّبَ القُلُوبِ ثَبِّتْ قَلْبِی عَلَی دِينِكَ

(O Transformer of Hearts, make my heart steadfast on faith.)

Hazrat Umm-e-Salamah^ra had enquired from the Holy Prophet^sa as to why he would repeat this prayer so often. He replied, “God is in total control of a person’s heart, as if the heart is held between His two fingers and He can turn it whenever He wants.”
