Prayers and Meditations — Paragraph 99
Source (Arabic)
إِلَيْكَ وَفِيْ السِّجْنِ يَدْعُوهُمْ إِلى شَطْرِ مَواهِبِكَ وَأَلْطافِكَ، كُلَّما ازْدادَ البَلايا إِنَّهُ زادَ فِيْ إِظْهارِ أَمْرِكَ وَإِعْلاءِ كَلِمَتِكَ، أَشْه
Translation
Thou seest, O my God, how, notwithstanding the swords that are drawn against Him, He calleth the nations unto Thee, and though Himself a prisoner summoneth them to turn in the direction of Thy gifts and bounties. With every fresh tribulation He manifested a fuller measure of Thy Cause, and exalted more highly Thy word.
