It was narrated from 'Ubaidullah bin 'Abdullah bin 'Umar that his father said

"The Talbiyah of the Messenger of Allah (ﷺ) was: "Labbaika Allahumma Labbaik, Labbaika la sharika laka labbaik. 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. Verily all praise and blessings are Yours, and all sovereignty, You have no partner)." And Ibn 'Umar added: "Labbaika Labbaika wasa'daika wal-khayr fi yadika, warraghba' ilaika wal-'aml (Here I am, here I am, and at Your service; all good is in Your hands, seeking Your pleasure and striving for Your sake)."
