Narrated Qatada:

I asked Anas (about the Prophet's 'Umra) and he replied, "The Prophet performed 'Umra when the pagans made him return, and Umra of al-Hudaibiya (the next year), and another 'Umra in Dhi-l-Qa'da, and another 'Umra in combination with his Hajj."

حَدَّثَنَا أَبُو الْوَلِيدِ، هِشَامُ بْنُ عَبْدِ الْمَلِكِ حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، قَالَ سَأَلْتُ أَنَسًا ـ رضى الله عنه ـ فَقَالَ اعْتَمَرَ النَّبِيُّ ﷺ حَيْثُ رَدُّوهُ، وَمِنَ الْقَابِلِ عُمْرَةَ الْحُدَيْبِيَةِ، وَعُمْرَةً فِي ذِي الْقَعْدَةِ وَعُمْرَةً مَعَ حَجَّتِهِ.
