Mishkat al-Masabih 10 The Rites of Pilgrimage كتاب المناسك 38

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

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.
