Prayers and Meditations — Paragraph 163
Source (Arabic)
إِنَّكَ أَنْتَ المُقْتَدِرُ القَدِيرُ وَبِالإِجابَةِ جَدِيرٌ، لا إِلهَ إِلاَّ أَنْتَ العَلِيمُ الخَبِيرُ.
Translation
Thou, in truth, art the God of strength and power, Who art meet to answer them that pray Thee. There is no God save Thee, the All-Knowing, the All-Wise.
