'Abdullah b. Shaqiq reported that 'Uthman (Allah be pleased with him) used to forbid Tamattu', whereas 'Ali (Allah be pleased with him) ordered to do it. 'Uthman said a word to 'Ali, but 'Ali said: You know that we used to perform Tamattu' with the Messenger of Allah ﷺ, whereupon he said: It is right, but we entertained fear. This hadith has been narrated by Shu'ba with the same chain of transmitters.

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالَ ابْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، قَالَ قَالَ عَبْدُ اللَّهِ بْنُ شَقِيقٍ كَانَ عُثْمَانُ يَنْهَى عَنِ الْمُتْعَةِ، وَكَانَ، عَلِيٌّ يَأْمُرُ بِهَا فَقَالَ عُثْمَانُ لِعَلِيٍّ كَلِمَةً ثُمَّ قَالَ عَلِيٌّ لَقَدْ عَلِمْتَ أَنَّا قَدْ تَمَتَّعْنَا مَعَ رَسُولِ اللَّهِ ﷺ فَقَالَ أَجَلْ وَلَكِنَّا كُنَّا خَائِفِينَ .
