عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّهَا قَالَتْ مَا رَفَعَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ رَأْسَهُ إِلَى السَّمَاءِ إِلَّا قَالَ يَا مُصَرِّفَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى طَاعَتِكَ
It is narrated from Sayyida Aisha (may Allah be pleased with her), she says: Whenever the Messenger of Allah (peace and blessings be upon him) raised his head towards the sky, he would supplicate: "Ya Musarrifal Quloob, thabbit qalbi 'ala ta'atik" (O Turner of the hearts! Turn my heart towards Your obedience).
