فَإِذَا دَخَلَ مَكَّةَ طَافَ وَسَعَى، وَلَمْ يَتَحَلَّلْ حَتَّى يُحْرِمَ بِالْحَجِّ يَوْمَ التَّرْوِيَةِ
Translation: On entering Makkah he performs tawaf and saʿi but does not exit ihram before entering the Hajj rite on the Day of Tarwiyah.
This is the brought-hady form: tawaf and saʿi for Umrah do not produce the ordinary interim release. Ihram continues when Hajj is subsequently added. It resembles qiran in continuation, but its initial ihram was for Umrah.
