Concept:Al-Mutamatti is the pilgrim who performs Hajj by the method of Tamattu'.
Explanation:Such a pilgrim first enters the state of Ihram for 'Umrah from the appointed Miqat.
He completes the 'Umrah rites, then comes out of Ihram.
After waiting in Makkah, he enters Ihram again for Hajj on the 8th day of Dhul-Hijjah.
So, al-mutamatti is one who performed 'Umrah and waited for Hajj and thereafter performed Hajj.

He is not simply a mutamir, because a mutamir only performs 'Umrah without proceeding to Hajj.
