It was narrated that 'Abdullah bin Masud said:"Part of the Talbiyah of the Messenger of Allah was 'Labbaika Allahumma labbbaik, Labbaika la sharika laka labbaik, Innal-hamda wan-ni'mata laka wal-mulk, (Here I am, O Allah, here I am. Here I am, You have no partner, here I am. Verily all praise and blessings are Yours)
