[Machine] I hear the Prophet ﷺ often invoking, saying, "O Transformer of hearts, make my heart firm on Your religion." I said, "O Messenger of Allah, is this a supplication that I can see and hear you repeating often?" He replied, "There is no person except that his heart is between two of the fingers of Allah's fingers, He can either strengthen or deviate it as He wills."  

أَسْمَعُ النَّبِيَّ ﷺ يُكْثِرُ أَنْ يَدْعُوَ بِهِ يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دَيْنِكَ قُلْتُ يَا رَسُولَ اللهِ دَعْوَةٌ أَرَاكَ وَأُسْمَعُكَ تَكْثُرُ أَنْ تَدْعُوَ بِهَا يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دَيْنِكَ قَالَ «لَيْسَ مِنْ آدَمِيٍّ إِلَّا وَقَلْبُهُ بَيْنَ إِصْبَعَيْنِ مِنْ أَصَابِعِ اللهِ إِنْ شَاءَ أَقَامَهُ وَإِنْ شَاءَ أَزَاغَهُ»
