Sahih Muslim 1232b
Bakr b. 'Abdullah reported: Anas (Allah be pleased with him) had narrated to us that he saw Allah's Apostle ﷺ 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 ﷺ جَمَعَ بَيْنَهُمَا بَيْنَ الْحَجِّ وَالْعُمْرَةِ قَالَ فَسَأَلْتُ ابْنَ عُمَرَ فَقَالَ أَهْلَلْنَا بِالْحَجِّ . فَرَجَعْتُ إِلَى أَنَسٍ فَأَخْبَرْتُهُ مَا قَالَ ابْنُ عُمَرَ فَقَالَ كَأَنَّمَا كُنَّا صِبْيَانًا .
