It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Talbiyah of the Messenger of Allah (peace and blessings be upon him) was: «لَبَّيْكَاللَّهُمَّلَبَّيْكَلَبَّيْكَلَاشَرِيكَلَكَلَبَّيْكَإِنَّالْحَمْدَوَالنِّعْمَةَلَكَوَالْمُلْكَلَاشَرِيكَلَكَ» "Here I am, O Allah, here I am. Here I am, You have no partner, here I am. All praise and all blessings are for You, and the sovereignty is Yours, You have no partner."
