Sahih Muslim 1226
Sahih Muslim · Book 15: The Book of Pilgrimage · The Permissibilty of Tamattu'
A hadith like this is transmitted on the authority of Imran b. Husain, but with this variation that he ('Imran) said:
وَحَدَّثَنِيهِ مُحَمَّدُ بْنُ حَاتِمٍ ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ ، عَنْ عِمْرَانَ الْقَصِيرِ ، حَدَّثَنَا أَبُو رَجَاءٍ عَنْ عِمْرَانَ بْنِ حُصَيْنٍ ، . بِمِثْلِهِ غَيْرَ أَنَّهُ قَالَ وَفَعَلْنَاهَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَلَمْ يَقُلْ وَأَمَرَنَا بِهَا .
We did that (Tamattu') in the company of Allah's Messenger (ﷺ) and he did not say anything but he (the Holy Prophet) commanded us to do it.
