I heard Allah's Apostle (way peace be upon him) pronouncing Talbiya for both Hajj and Umra. Bakr (one of the narrators) said: I narrated it to Ibn 'Umar, whereupon he said: He (the Holy Prophet) pronounced the Talbiya for Hajj alone. I met Anas and narrated to him the words of Ibn 'Umar, whereupon he said: You treat us not but only as children. I heard Messenger of Allah ﷺ pronouncing Talbiya both for 'Umra and Hajj. (Using translation from Muslim 1232a)
سَمِعْتُ النَّبِيَّ ﷺ يُلَبِّي بِالْعُمْرَةِ وَالْحَجِّ جَمِيعًا فَحَدَّثْتُ بِذَلِكَ ابْنَ عُمَرَ فَقَالَ لَبَّى بِالْحَجِّ وَحْدَهُ فَلَقِيتُ أَنَسًا فَحَدَّثْتُهُ بِقَوْلِ ابْنِ عُمَرَ فَقَالَ أَنَسٌ مَا تَعُدُّونَا إِلَّا صِبْيَانًا سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «لَبَّيْكَ عُمْرَةً وَحَجًّا مَعًا»
