From Sahih Bukhari (Hadith 1549):
Narrated `Abdullah bin `Umar:The Talbiya of Allah's Messenger (ﷺ) was : 'Labbaika Allahumma labbaik, Labbaika la sharika Laka labbaik, Inna-l-hamda wan-ni'mata Laka walmulk, La sharika Laka' (I respond to Your call O Allah, I respond to Your call, and I am obedient to Your orders, You have no partner, I respond to Your call All the praises and blessings are for You, All the sovereignty is for You, And You have no partners with You)
