رِضاكَ، وَإِنَّكَ أَنْتَ المُقَدَّسُ عَمَّا سِواكَ وَإِنَّكَ أَنْتَ الشَّافِي الكَافِي الحافِظُ الغَفُورُ الرَّحِيمُ.
Translation
Thou, in truth, art immensely exalted above all else except Thyself. Thou art, verily, the Healer, the All-Sufficing, the Preserver, the Ever-Forgiving, the Most Merciful.
