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