There was revealed the verse of Tamattu' in Hajj in the Book of Allah and the Messenger of Allah ﷺ commanded us to perform it. and then no verse was revealed abrogating the Tamattu' (form of Hajj), and the Messenger of Allah ﷺ did not forbid to do it till he died. So whatever a person said was his personal opinion. (Using translation from Muslim 1226i)
عِمْرَانُ بْنُ حُصَيْنٍ «نَزَلَتْ آيَةُ الْمُتْعَةِ فِي كِتَابِ اللهِ يَعْنِي مُتْعَةَ الْحَجِّ فَأُمِرَ بِهَا رَسُولُ اللهِ ﷺ وَلَمْ تَنْزِلْ آيَةٌ تَنْسَخُ آيَةَ مُتْعَةِ الْحَجِّ وَلَمْ يَنْهَ رَسُولُ اللهِ ﷺ عَنْهَا حَتَّى مَاتَ قَالَ رَجُلٌ بِرَأْيِهِ مَا شَاءَ»
