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.
عِمْرَانُ بْنُ حُصَيْنٍ نَزَلَتْ آيَةُ الْمُتْعَةِ فِي كِتَابِ اللَّهِ يَعْنِي مُتْعَةَ الْحَجِّ وَأَمَرَنَا بِهَا رَسُولُ اللَّهِ ﷺ ثُمَّ لَمْ تَنْزِلْ آيَةٌ تَنْسَخُ آيَةَ مُتْعَةِ الْحَجِّ وَلَمْ يَنْهَ عَنْهَا رَسُولُ اللَّهِ ﷺ حَتَّى مَاتَ قَالَ رَجُلٌ بِرَأْيِهِ بَعْدُ مَا شَاءَ
