وَإِذَا عَادَ الْمُتَمَتِّعُ إِلَى بَلَدِهِ بَعْدَ فَرَاغِهِ مِنَ الْعُمْرَةِ، وَلَمْ يَكُنْ سَاقَ الْهَدْيَ، بَطَلَ تَمَتُّعُهُ
Translation: If the mutamatti returns to his own town after Umrah without having brought the sacrificial offering, the legal classification as tamattu ceases.
“His tamattu ceases” does not mean his completed Umrah becomes invalid. It means the special legal combination into a tamattu journey is lost. The clause expressly specifies that he had not brought a hady.
