Sahih Muslim Book - 15, Hadith - 2996

وَحَدَّثَنِى أُمَيَّةُ بْنُ بِسْطَامَ الْعَيْشِىُّ حَدَّثَنَا يَزِيدُ - يَعْنِى ابْنَ زُرَيْعٍ - حَدَّثَنَا حَبِيبُ بْنُ الشَّهِيدِ عَنْ بَكْرِ بْنِ عَبْدِ اللَّهِ حَدَّثَنَا أَنَسٌ رضى الله عنه أَنَّهُ رَأَى النَّبِىَّ -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.

It was narrated from Bakr bin Abdullah: “Anas [may Allah be pleased with them] told us that he saw the Messenger of Allah (SAW) joining them” – Hajj and Umrah – he said: “I asked Ibn Umar and he said: ‘We entered Ihram for Hajj.’ I went back to Anas and told him what Ibn Umar had said, and he said ‘it is as if we were little children.’
