لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ، لَبَّيْكَ لاَ شَرِيكَ لَكَ لَبَّيْكَ، إِنَّ الْحَمْدَ والنِّعْمَة لَكَ والمُلْكُ، لَا شَرِيكَ لَكَ

Transliteration:

Labbayk-Allāhumma labbayk, labbayka lā sharīka laka labbayk, inna ‘l-ḥamda, wanni`mata, laka wa ‘l-mulk, lā sharīka lak.

Translation:

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.
