Sahih Muslim Book - 15, Hadith - 2974

وَحَدَّثَنِى عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ حَدَّثَنَا أَبِى حَدَّثَنَا شُعْبَةُ عَنْ حُمَيْدِ بْنِ هِلاَلٍ عَنْ مُطَرِّفٍ قَالَ قَالَ لِى عِمْرَانُ بْنُ حُصَيْنٍ أُحَدِّثُكَ حَدِيثًا عَسَى اللَّهُ أَنْ يَنْفَعَكَ بِهِ إِنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- جَمَعَ بَيْنَ حَجَّةٍ وَعُمْرَةٍ ثُمَّ لَمْ يَنْهَ عَنْهُ حَتَّى مَاتَ وَلَمْ يَنْزِلْ فِيهِ قُرْآنٌ يُحَرِّمُهُ وَقَدْ كَانَ يُسَلَّمُ عَلَىَّ حَتَّى اكْتَوَيْتُ فَتُرِكْتُ ثُمَّ تَرَكْتُ الْكَىَّ فَعَادَ.

It was narrated that Mutarrif said: “Imran bin Husain said to me: ‘I will tell you a hadith, by means of which Allah will benefit you after today. The Messenger of Allah (SAW) joined Hajj and Umrah, then he did not forbid it until he died, and no Quran (Ayat) was revealed forbidding that. And I was always greeted until I was cauterized, then the greetings ceased, then when I stopped (being cauterized), the greeting returned.
