Hadith 435
Sayyiduna Ibn Umar (may Allah be pleased with them both) says: The Talbiyah of the Messenger of Allah (peace and blessings be upon him) was as follows: "Labbayka Allahumma labbayk, labbayka la sharika laka labbayk, innal-hamda wan-ni‘mata laka wal-mulk, la sharika lak." "Here I am, O Allah! Here I am. Here I am, You have no partner, here I am. Surely all praise and blessings are for You, and the kingdom (as well), You have no partner."
