Sahih Muslim 1226 a
Mutarrif reported:
'Imran b. Husain said to me: Should I not narrate to you a hadith today by which Allah will benefit you subsequently-and bear in mind that Allah's Messenger (ﷺ) made some members of his family perform 'Umra within ten days of Dhu'l-Hijja. No verse was revealed to abrogate that, and he (the Holy Prophet) did not refrain from doing it till he died. So after him everyone said as he liked, (but it would be his. personal opinion and not the verdict of the Shari'ah).
وَحَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا الْجُرَيْرِيُّ، عَنْ أَبِي، الْعَلاَءِ عَنْ مُطَرِّفٍ، قَالَ قَالَ لِي عِمْرَانُ بْنُ حُصَيْنٍ إِنِّي لأُحَدِّثُكَ بِالْحَدِيثِ الْيَوْمَ يَنْفَعُكَ اللَّهُ بِهِ بَعْدَ الْيَوْمِ وَاعْلَمْ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَدْ أَعْمَرَ طَائِفَةً مِنْ أَهْلِهِ فِي الْعَشْرِ فَلَمْ تَنْزِلْ آيَةٌ تَنْسَخُ ذَلِكَ وَلَمْ يَنْهَ عَنْهُ حَتَّى مَضَى لِوَجْهِهِ ارْتَأَى كُلُّ امْرِئٍ بَعْدُ مَا شَاءَ أَنْ يَرْتَئِيَ ‏.‏
