O Turner of hearts
اللَّهُمَّ مُصَرِّفَ الْقُلُوبِ صَرِّفْ قُلُوبَنَا عَلَى طَاعَتِكَ
Allahumma musarrifa-l-qulubi sarrif qulubana 'ala ta'atik.
"O Allah, Turner of hearts, turn our hearts to obeying You."
Narrated by Abdullah ibn Amr. Sahih Muslim 2655
A short reflection
He said it straight after teaching that every heart is in the hand of the Most Merciful. Hearts turn; ask the One who turns them.
