اللَّهُمَّ لَكَ رَكَعْتُ، وَبِكَ آمَنْتُ، وَلَكَ أَسْلَمْتُ خَشَعَ لَكَ سَمْعِي، وَبَصَرِي وَمُخِّي، وَعَظْمِي، وَعَصَبِي، وَمَا اسْتَقَلَّ بِهِ قَدَمِي
Allaahumma laka raka’tu, wa bika ‘aamantu, wa laka ‘aslamtu khasha’a laka sam’ee, wa basaree, wa mukhkhee, wa ‘adhmee, wa ‘asabee, wa mastaqalla bihi qadamee
O Allah! to You I bow (in prayer) and in You I believe and to You I have submitted. Before You my hearing is humbled, as is my sight, my mind, my bones, my nerves and what my feet have mounted upon (for travel).
Muslim 1:534
