3522. Shahr bin Hawshab said: "I said to Umm Salamah: 'O Mother of the Believers! What was the supplication that the Messenger of Allāh ﷺ said most frequently when he was with you?' She said: 'The supplication he said most frequently was: "O Changer of the hearts, make my heart firm upon Your religion (Yā Muqallibal-Qulūb, Thabbit Qalbi 'Alā Dinik).'" She said: 'So I said: "O Messenger of Allāh, why do you supplicate so frequently: 'O Changer of the hearts, make my heart firm upon Your religion.' He said: 'O Umm Salamah! Verily, there is no human being except that his heart is between Two Fingers of the Fingers of Allāh, so whomever He wills He makes steadfast, and whomever He wills He causes to deviate.'" (Hasan) So (one of the narrators) Mu'adh recited: O our Lord, do not cause our hearts to deviate after You have guided us.[1] [He said:] There are narrations on this topic from 'Āishah, An-Nawwās bin Sam'ān, Anas, Jābir, 'Abdullāh bin 'Amr, and Nu'aim bin [Hammār]. [Abū 'Eisā said:] This Ḥadīth is Hasan.
