Muwatta Imam Malik Book of Hajj, Hadith 66

Yahya related to me from Malik, from Sumayy, the mawla of Abu Bakr ibn Abd ar-Rahman, from Abu Salih as-Samman, from Abu Hurayra, that the Messenger of Allah, may Allah bless him and grant him peace ,said, "Umra is an expiation for what is between it and the next umra, and the only reward for an accepted hajj is the Garden."

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ سُمَىٍّ، مَوْلَى أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِي صَالِحٍ السَّمَّانِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " الْعُمْرَةُ إِلَى الْعُمْرَةِ كَفَّارَةٌ لِمَا بَيْنَهُمَا وَالْحَجُّ الْمَبْرُورُ لَيْسَ لَهُ جَزَاءٌ إِلاَّ الْجَنَّةُ " .
