حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ مُحَمَّدِ بْنِ عَبْدِ اللَّهِ بْنِ الْحَارِثِ بْنِ نَوْفَلِ بْنِ عَبْدِ الْمُطَّلِبِ، أَنَّهُ حَدَّثَهُ أَنَّهُ، سَمِعَ سَعْدَ بْنَ أَبِي وَقَّاصٍ، وَالضَّحَّاكَ بْنَ قَيْسٍ، عَامَ حَجَّ مُعَاوِيَةُ بْنُ أَبِي سُفْيَانَ - وَهُمَا يَذْكُرَانِ التَّمَتُّعَ بِالْعُمْرَةِ إِلَى الْحَجِّ - فَقَالَ الضَّحَّاكُ بْنُ قَيْسٍ لاَ يَفْعَلُ ذَلِكَ إِلاَّ مَنْ جَهِلَ أَمْرَ اللَّهِ عَزَّ وَجَلَّ ‏.‏ فَقَالَ سَعْدٌ بِئْسَ مَا قُلْتَ يَا ابْنَ أَخِي ‏.‏ فَقَالَ الضَّحَّاكُ فَإِنَّ عُمَرَ بْنَ الْخَطَّابِ قَدْ نَهَى عَنْ ذَلِكَ ‏.‏ فَقَالَ سَعْدٌ قَدْ صَنَعَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم وَصَنَعْنَاهَا مَعَهُ ‏.‏

Yahya related to me from Malik, from Ibn Shihab, that Muhammadibn Abdullah ibn al-Harith ibn Nawfal ibn Abd al-Muttalib told himthat he had heard Sad ibn Abi Waqqas and ad-Dahhak ibn Qays discussingtamattu in between umra and hajj. Ad-Dahhak ibn Qays said, "Onlysomeone who is ignorant of what Allah, the Exalted and Glorified, sayswould do that." Whereupon Sad said, "How wrong is what you have justsaid, son of my brother!" Ad-Dahhak said, ''Umar ibn al-Khattabforbade that," and Sad said, "The Messenger of Allah, may Allah blesshim and grant him peace, did it, and we did it with him." Translation Not Available
