Prayers and Meditations — Paragraph 443
Source (Arabic)
أَنْتَ المُقْتَدِرُ عَلَى ما تَشَاءُ، لا إِلهَ إِلاَّ أَنْتَ القَادِرُ العالِمُ الحَاكِمُ المُهَيْمِنُ القَيُّومُ.
Translation
Powerful art Thou to do what Thou pleasest. No God is there beside Thee, the All-Powerful, the Omniscient, the Supreme Ruler, the Help in Peril, the Self-Subsisting.
