Mishkat al-Masabih 2544
Anas said:
I was riding behind Abu Talha, and the people were crying aloud for both of them, the hajj and the ‘umra . 

Bukhari transmitted it.
وَعَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: كُنْتُ رَدِيفَ أَبِي طَلْحَةَ وَإِنَّهُمْ لَيَصْرُخُونَ بهِما جَمِيعًا: الْحَج وَالْعمْرَة. رَوَاهُ البُخَارِيّ
