Prayers and Meditations — Paragraph 403
Source (Arabic)
يا إِلهِي عَبْدَكَ الَّذِيْ آمَنَ بِكَ عَلَى نُصْرَةِ أَمْرِكَ، ثُمَّ احْفَظْهُ فِي كَنَفِ حِفْظِكَ وَحِمايَتِكَ فِي الآخِرَةِ وَالأُولى وَإِنَّكَ أَنْتَ الحَاكِمُ عَلَى ما تَشآءُ لا إِلهَ إِلاَّ أَنْتَ الغَفُورُ الْكَرِيمُ.
Translation
Make steadfast Thou, O my God, Thy servant who hath believed in Thee to help Thy Cause, and keep him safe from all dangers in the stronghold of Thy care and Thy protection, both in this life and in the life which is to come. Thou, verily, rulest as Thou pleasest. No God is there save Thee, the Ever-Forgiving, the Most Generous.
