The Talbiya for the one doing Hajj or 'Umrah

Labbayk-Allāhumma labbayk, labbayka lā sharīka laka labbayk, inna ‘l-ḥamda, wanni`mata, laka wa ‘l-mulk, lā sharīka lak. 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. Reference: Al-Bukhari, cf. Al-Asqalani, Fathul-Bari 3/408, Muslim 2/841.
