191. At the beginning of the prayer #7
لَبَّيْكَ وَسَعْدَيْكَ، وَالْخَيْرُ كُلُّهُ بِيَـدَيْكَ، وَالشَّـرُّ لَيْسَ إِلَيْـكَ، أَنَا بِكَ وَإِلَيْكَ، تَبَارَكْتَ وَتَعَالَيْتَ، أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ
Labbayka wa sa'dayka, wal-khayru kulluhu biyadaika, washsharru laysa ilayka, anaa bika wa-ilayka, tabaarakta wa ta'Aalayta, astaghfiruka wa-atoobu ilayk
Here I am, in answer to Your call, happy to serve you. All good is within Your hands and evil does not stem from You. I exist by your will and will return to you. Blessed and High are You, I seek Your forgiveness and repent unto You.
