"Mu'awiyah saide to Ibmn 'Abbas: "do you know that I cut the hair of the Messenger of Allah at Al-Marwah?" He said: "No." Ibn 'Abbas said: "This Mu'awiyah forbids the people to perform Tamattu' but the Prophet performed Tamattue." (Using translation from Nasāʾī 2737)
قَالَ مُعَاوِيَةُ لِابْنِ عَبَّاسٍ أَعَلِمْتَ أَنِّي قَصَّرْتُ مِنْ رَأْسِ رَسُولِ اللهِ ﷺ عِنْدَ الْمَرْوَةِ؟ قَالَ لَا يَقُولُ ابْنُ عَبَّاسٍ هَذِهِ عَلَى مُعَاوِيَةَ «أَنْ يَنْهَى النَّاسَ عَنِ الْمُتْعَةِ وَقَدْ تَمَتَّعَ رَسُولُ اللهِ ﷺ»
