Jami` at-Tirmidhi 826

Nafi` narrated:When Ibn Umar would say the talbiyah he would continue saying: "Labbaik Allahumma labbaik. Labbaik la sharika laka labbaik. Innal-hamda wan-ni`mata laka wal-mulk, la sharika laka" (I respond to Your call O Allah! I respond to Your call, You have no partner, I respond to You call. All praise, thanks and blessings are for You. And You have no partners with You). He said: "Abdullah bin Umar would say: 'This is the Talbiyah of the Messenger of Allah.' He would himself add the following after the Talbiyah of the Messenger of Allah: "Labbaik labbaika wa-sa'daik, wal-khairuu fi yadaik. Labbaika war-raghba'u ilaika wal-amal" ('I respond to Your call, and I am obedient to Your orders, all good is in Your Hands. I respond to Your call and the requests and deeds are for You)
