ahmad:26133ʿAbd al-Ṣamad And ʿAffān > Ḥammād b. Salamah > ʿAlī b. Zayd > Um Muḥammad > ʿĀʾishah

[Machine] "That the Messenger of Allah, ﷺ , often used to say, 'O Turner of hearts, make my heart steadfast upon Your religion and obedience to You.' It was said to him, 'O Messenger of Allah, why do you often say, 'O Turner of hearts, make my heart steadfast upon Your religion and obedience to You'? He replied, 'Verily, it is the one who turns the hearts and hearts of people are between two fingers of the Most Merciful. When He wants, He turns the heart of a servant.' He said, 'Verily, [it is] between two fingers of the fingers of Allah, the Most High.'"  

أحمد:٢٦١٣٣حَدَّثَنَا عَبْدُ الصَّمَدِ وَعَفَّانُ قَالَا حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ قَالَ حَدَّثَنَا عَلِيُّ بْنُ زَيْدٍ عَنْ أُمِّ مُحَمَّدٍ عَنْ عَائِشَةَ

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يُكْثِرُ أَنْ يَقُولَ يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دِينِكَ وَطَاعَتِكَ فَقِيلَ لَهُ يَا رَسُولَ اللهِ قَالَ عَفَّانُ فَقَالَتْ لَهُ عَائِشَةُ إِنَّكَ تُكْثِرُ أَنْ تَقُولَ يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دِينِكَ وَطَاعَتِكَ قَالَ وَمَا يُؤْمِنِّي وَإِنَّمَا قُلُوبُ الْعِبَادِ بَيْنَ أُصْبُعَيِ الرَّحْمَنِ إِنَّهُ إِذَا أَرَادَ أَنْ يُقَلِّبَ قَلْبَ عَبْدٍ قَلَّبَهُ قَالَ عَفَّانُ بَيْنَ أُصْبُعَيْنِ مِنْ أَصَابِعِ اللهِ ﷻ
