Narrated Marwan bin Al-Hakam:
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ ، حَدَّثَنَا غُنْدَرٌ ، حَدَّثَنَا شُعْبَةُ ، عَنِ الْحَكَمِ ، عَنْ عَلِيِّ بْنِ حُسَيْنٍ ، عَنْ مَرْوَانَ بْنِ الْحَكَمِ ، قَالَ شَهِدْتُ عُثْمَانَ وَعَلِيًّا ـ رضى الله عنهما ـ وَعُثْمَانُ يَنْهَى عَنِ الْمُتْعَةِ وَأَنْ يُجْمَعَ بَيْنَهُمَا. فَلَمَّا رَأَى عَلِيٌّ، أَهَلَّ بِهِمَا لَبَّيْكَ بِعُمْرَةٍ وَحَجَّةٍ قَالَ مَا كُنْتُ لأَدَعَ سُنَّةَ النَّبِيِّ صلى الله عليه وسلم لِقَوْلِ أَحَدٍ.
I saw `Uthman and `Ali. `Uthman used to forbid people to perform Hajj-at-Tamattu` and Hajj-al- Qiran (Hajj and `Umra together), and when `Ali saw (this act of `Uthman), he assumed Ihram for Hajj and `Umra together saying, "Lubbaik for `Umra and Hajj," and said, "I will not leave the tradition of the Prophet (ﷺ) on the saying of somebody."
