حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْوَهَّابِ، حَدَّثَنَا أَيُّوبُ، عَنْ أَبِي قِلاَبَةَ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ كُنْتُ رَدِيفَ أَبِي طَلْحَةَ، وَإِنَّهُمْ لَيَصْرُخُونَ بِهِمَا جَمِيعًا الْحَجِّ وَالْعُمْرَةِ.
Narrated Anas:
I was riding behind Abu Talha (on the same) riding animal and (the Prophet's companions) were reciting Talbiya aloud for both Hajj and `Umra.
