Sahih Muslim 1217
Sahih Muslim · Book 15: The Book of Pilgrimage · Tamattu with Hajj and Umrah
Qatada narrated this hadith with the same chain of transmitters saying:
وَحَدَّثَنِيهِ زُهَيْرُ بْنُ حَرْبٍ ، حَدَّثَنَا عَفَّانُ ، حَدَّثَنَا هَمَّامٌ ، حَدَّثَنَا قَتَادَةُ ، بِهَذَا الإِسْنَادِ وَقَالَ فِي الْحَدِيثِ فَافْصِلُوا حَجَّكُمْ مِنْ عُمْرَتِكُمْ فَإِنَّهُ أَتَمُّ لِحَجِّكُمْ وَأَتَمُّ لِعُمْرَتِكُمْ .
(That 'Umar also said): Separate your Hajj from 'Umra, for that is the most complete Hajj, and complete your Umra.
