Context
We relate in the book of at-Tirmidhī that Shahr ibn Ḥawshab narrated that he asked Umm Salamah 
: “Mother of the Believers, what was the most frequent du‘ā’ of Allah’s Messenger 
when he was with you?” She replied: “His most frequent du‘ā’ was: ‘O Overturner of hearts, make my heart firm in Your religion.’” [38].At-Tirmidhī says that this hadith is ḥasan.
