اَللَّهُمَّ مُصَرِّفَ الْقُلُوبِ صَرِّفْ قُلُوبَنَا عَلَى طَاعَتِكَ

Allaahumma musarrifal-qulubi, sarrif qulubana 'ala ta'atik

Abdullah bin Amr bin al-'As (RA) reported that he heard Allah's Messenger (ﷺ) as saying: Verily, the hearts of all the sons of Adam are between the two fingers out of the fingers of the Compassionate Lord as one heart. He turns that to any (direction) He likes. Then Allah’s Messenger (ﷺ) said: (Dua mentioned above)
