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 " .
English Translation
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 (ﷺ) pronouncing Talbiya both for 'Umra and Hajj
