Sahih Muslim , Hadith 1232

Anas (Allah be pleased with him) said: 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 Allah's Messenger pronouncing Talbiya both for 'Umra and Hajj.

وَحَدَّثَنَا سُرَيْجُ بْنُ يُونُسَ، حَدَّثَنَا هُشَيْمٌ، حَدَّثَنَا حُمَيْدٌ، عَنْ بَكْرٍ، عَنْ أَنَسٍ، - رضى الله عنه - قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يُلَبِّي بِالْحَجِّ وَالْعُمْرَةِ جَمِيعًا ‏.‏ قَالَ بَكْرٌ فَحَدَّثْتُ بِذَلِكَ ابْنَ عُمَرَ فَقَالَ لَبَّى بِالْحَجِّ وَحْدَهُ ‏.‏ فَلَقِيتُ أَنَسًا فَحَدَّثْتُهُ بِقَوْلِ ابْنِ عُمَرَ فَقَالَ أَنَسٌ مَا تَعُدُّونَنَا إِلاَّ صِبْيَانًا سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ لَبَّيْكَ عُمْرَةً وَحَجًّا ‏" ‏ ‏.‏

Bakr b. 'Abdullah reported: Anas (Allah be pleased with him) had narrated to us that he saw Allah's Apostle combining Hajj and 'Umra. He (Bakr) said: I asked (about it) from Ibn 'Umar, whereupon he said: We entered into the state of Ihram for Hajj (only). I came to Anas and told him what Ibn Umar had said, whereupon he remarked: (You are treating us) as if we were children.

وَحَدَّثَنِي أُمَيَّةُ بْنُ بِسْطَامَ الْعَيْشِيُّ، حَدَّثَنَا يَزِيدُ، - يَعْنِي ابْنَ زُرَيْعٍ - حَدَّثَنَا حَبِيبُ، بْنُ الشَّهِيدِ عَنْ بَكْرِ بْنِ عَبْدِ اللَّهِ، حَدَّثَنَا أَنَسٌ، رضى الله عنه أَنَّهُ رَأَى النَّبِيَّ صلى الله عليه وسلم جَمَعَ بَيْنَهُمَا بَيْنَ الْحَجِّ وَالْعُمْرَةِ قَالَ فَسَأَلْتُ ابْنَ عُمَرَ فَقَالَ أَهْلَلْنَا بِالْحَجِّ ‏.‏ فَرَجَعْتُ إِلَى أَنَسٍ فَأَخْبَرْتُهُ مَا قَالَ ابْنُ عُمَرَ فَقَالَ كَأَنَّمَا كُنَّا صِبْيَانًا ‏.‏
