Its description is that one enters the state of ihram for 'Umrah in the months of Hajj, completes it, and then enters the state of ihram for Hajj in that same year.

The Shaykh : Then he said "Its description" the description of tamattu' "is that one enters the state of ihram for 'Umrah in the months of Hajj, completes it, and then enters the state of ihram for Hajj in that same year" Pay attention to the conditions. Hajj is not considered tamattu' unless these descriptions are combined: one must enter the state of ihram for 'Umrah in the months of Hajj. The months of Hajj are Shawwal, Dhu al-Qa'dah, and Dhu al-Hijjah. So, if one enters the state of ihram for 'Umrah in Ramadan and completes it in Shawwal, he is not a mutamatti' (one performing tamattu'). Why? Because he did not enter the state of ihram for it in the months of Hajj. And if one enters the state of ihram for it in Shawwal, is he a mutamatti'? Why? Because he entered the state of ihram for it in the months of Hajj. And if one enters the state of ihram for it in Ramadan and completes it in Ramadan, and remains until Hajj, he is not a mutamatti'. So, there are three scenarios: one enters the state of ihram for 'Umrah before the months of Hajj and completes it in the months of Hajj; one enters the state of ihram for 'Umrah in the months of Hajj; one enters the state of ihram for 'Umrah and completes it before the months of Hajj. Who is not a mutamatti'? The first and the second. The one who entered the state of ihram for 'Umrah in Ramadan and completed it in Shawwal is not a mutamatti'. The one who entered the state of ihram for 'Umrah in Ramadan and completed it in Ramadan? He is not a mutamatti'. The one who entered the state of ihram for 'Umrah in Shawwal and completed it in Shawwal? He is a mutamatti'. This is the first point. Second, "and completes it." One completes the 'Umrah by performing tawaf, sa'y, and shortening the hair. Here, shortening the hair is better than shaving for two reasons. The first is that the Prophet (peace and blessings be upon him) ordered those who did not bring sacrificial animals to shorten their hair. The second is that it is so that there remains hair for Hajj to shave or shorten. If he shaved and the period is short, the hair would not be available for Hajj... from it "then he enters the state of ihram for Hajj in that same year" "Then" means after completing it, exiting the state of ihram, and enjoying what Allah has made lawful for him, he enters the state of ihram for Hajj in that same year. If he performed 'Umrah in the months of Hajj in the year 13 and performed Hajj in the year 14, what do you say?
The attendee: He is not a mutamatti'.

The Shaykh : He is not a mutamatti' because it is necessary that he enters the state of ihram for Hajj in that same year. This is the mutamatti'.
