Prayers and Meditations — Paragraph 656
Source (Arabic)
بِأَمْرِكَ تُبَدَّلُ الذِّلَّةُ بِالعِزَّةِ وَالضَّعْفُ بِالقُوَّةِ وَالعَجْزُ بِالاقْتِدارِ وَالاضْطِرابُ بِالاطْمِئْنانِ وَالرَّيْبُ بِالإِيْقانِ، لا إِلهَ إِلاَّ
Translation
Thou art He Who changeth through His bidding abasement into glory, and weakness into strength, and powerlessness into might, and fear into calm, and doubt into certainty. No God is there but Thee, the Mighty, the Beneficent.
