The pilgrim's announcement of his arrival for Hajj or 'Umrah
 

لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ ، لا شَرِيكَ لَكَ لَبَّيْكَ ،إنَّ الْحَمْدَ ،وَالنِّعْمَةَ ،لَكَ وَالْمُلْكُ ، لا شَرِيكَ لَكَ
 

233. Labbayk Allaahumma labbayk, labbayk laa shareeka laka labbayk, 'innal-hamda, wanni'mata, laka walmulk, laa shareeka laka.

I am here at Your service , O Allah , I am here at Your service. I am here at Your service, You have no partner, I am here at Your service . Surely the praise , and blessings are Yours , and the dominion . You have no partner.
