Ali Albarghouthi

Umm Salamah was asked: What was the most frequent dua of the Prophet salla Allah alayhi wa sallam when he was with you? She said: His most frequent dua was O Turner of the hearts, make my heart firm upon your religion. She said: O Messenger of Allah, why is O Turner of the hearts, make my heart firm upon your religion your most frequent dua? He said: O Umm Salamah, there is no human except that their heart is between Two Fingers of the Fingers of Allah, so whomever He wills He makes steadfast, and whomever He wills He leads astray. Then Muadh [one of the narrators of the hadith] recited: (O Our Rabb, do not lead our hearts astray after you have guided us [Aal Imran (8)])
