Hisn al-Muslim (Fortress of the Muslim) 36
((اللَّهُمَّ لَكَ رَكَعْتُ، وَبِكَ آمَنْتُ، وَلَكَ أَسْلَمْتُ، خَشَعَ لَكَ سَمْعِي، وَبَصَرِي، وَمُخِّي، وَعَــــظْمِي، وَعَصَبِي، [وَمَا استَقَلَّتْ بِهِ قَدَمِي])).
(O Allah, unto You I have bowed, and in You I have believed, and to You I have submitted. My hearing, sight, mind, bones, tendons and what my feet carry are humbled before You.)
