“I said to Umm Salamah: ‘O Mother of the Believers! What was the supplication that the Messenger of Allah 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 qalbī ʿalā dīnik).’” She said: ‘So I said: “O Messenger of Allah, 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 Allah, so whomsoever He wills He makes steadfast, and whomever He wills He causes to deviate.’”

قُلْتُ لأُمِّ سَلَمَةَ يَا أُمَّ الْمُؤْمِنِينَ مَا كَانَ أَكْثَرُ دُعَاءِ رَسُولِ اللَّهِ ﷺ إِذَا كَانَ عِنْدَكِ قَالَتْ كَانَ أَكْثَرُ دُعَائِهِ يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دِينِكَ قَالَتْ قُلْتُ يَا رَسُولَ اللَّهِ مَا لأَكْثَرِ دُعَائِكَ يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دِينِكَ قَالَ يَا أُمَّ سَلَمَةَ إِنَّهُ لَيْسَ آدَمِيٌّ إِلاَّ وَقَلْبُهُ بَيْنَ أُصْبُعَيْنِ مِنْ أَصَابِعِ اللَّهِ فَمَنْ شَاءَ أَقَامَ وَمَنْ شَاءَ أَزَاغَ فَتَلاَ مُعَاذٌ ( ربَّنَا لاَ تُزِغْ قُلُوبَنَا بَعْدَ إِذْ هَدَيْتَنَا ) قَالَ وَفِي الْبَابِ عَنْ عَائِشَةَ وَالنَّوَّاسِ بْنِ سَمْعَانَ وَأَنَسٍ وَجَابِرٍ وَعَبْدِ اللَّهِ بْنِ عَمْرٍو وَنُعَيْمِ بْنِ هَمَّارٍ قَالَ وَهَذَا حَدِيثٌ حَسَنٌ

“I said to Umm Salamah: ‘O Mother of the Believers! What was the supplication that the Messenger of Allah 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 qalbī ʿalā dīnik).’” She said: ‘So I said: “O Messenger of Allah, why do you supplicate so frequently: ‘O Changer of the hearts, make my heart firm upon Your religion.’ He said: ‘O Umm Salamah!

قُلْتُ لِأُمِّ سَلَمَةَ يَا أُمَّ الْمُؤْمِنِينَ مَا كَانَ أَكْثَرَ دُعَاءِ رَسُولِ اللهِ ﷺ إِذَا كَانَ عِنْدَكِ؟ قَالَتْ كَانَ أَكْثَرُ دُعَائِهِ يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دِينِكَ قَالَتْ فَقُلْتُ لَهُ يَا رَسُولَ اللهِ مَا أَكْثَرَ دُعَاءَكَ يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دِينِكَ؟ قَالَ يَا أُمَّ سَلَمَةَ إِنَّهُ لَيْسَ مِنْ آدَمِيٍّ إِلَّا وَقَلْبُهُ بَيْنَ أُصْبُعَيْنِ مِنْ أَصَابِعِ اللهِ ﷻ مَا شَاءَ أَقَامَ وَمَا شَاءَ أَزَاغَ قَالَ عَبْدُ اللهِ سَأَلْتُ أَبِي عَنْ أَبِي كَعْبٍ؟ فَقَالَ ثِقَةٌ وَاسْمُهُ عَبْدُ رَبِّهِابْنُ عُبَيْدٍ

[Machine] The Messenger of Allah ﷺ used to frequently say, "O Turner of hearts, keep my heart steadfast on your religion." So, I said, "O Messenger of Allah, why do you frequently make this supplication?" He replied, "O Umm Salamah, surely the heart of the son of Adam is between two fingers of the fingers of the Most Merciful. He turns it in the direction He wills."

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يُكْثِرُ أَنْ يَقُولَ «يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دِينِكَ» فَقُلْتُ يَا رَسُولَ اللهِ مَا أَكْثَرَ مَا تَدْعُو بِهَذَا الدُّعَاءِ؟ فَقَالَ «يَا أُمَّ سَلَمَةَ إِنَّ قَلْبَ ابْنِ آدَمَ بَيْنَ أُصْبُعَيْنِ مِنْ أَصَابِعِ رَبِّ الْعَالَمِينَ إِذَا شَاءَ أَقَامَهُ وَإِذَا شَاءَ أَزَاغَهُ»
