Musannaf Ibn Abi Shaybah 13957 — How the talbiyah is said

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) entered ihram and recited this talbiyah of tawhid (the Oneness of Allah): 'Labbayka Allahumma labbayk, labbayka la sharika laka labbayk, inna al-hamda wa al-ni'mata laka wa al-mulk, la sharika lak' (Here I am, O Allah, here I am; here I am, You have no partner, here I am; truly all praise and blessing are Yours, and the dominion; You have no partner).
