What is the ruling on someone who entered ihram for Umrah with the intention of performing Hajj (mutamatti') from the miqat, performed Umrah, but did not exit ihram from it, rather remained in ihram and intended it for Hajj?

If the mutamatti' (one performing Hajj al-Tamattu') enters into the state of ihram for Hajj directly with the ihram garments of 'Umrah after performing tawaf and sa'y, and then shaves or shortens his hair, there is nothing upon him. His 'Umrah and Hajj are valid, and he must offer the damm (sacrifice) for tamattu'.

However, if he enters into ihram for Hajj after performing tawaf and sa'y, but before shaving or shortening his hair, scholars have differed:

1. The well-known view of the (Hanbali) madhhab: His Hajj is invalid because he entered Hajj into 'Umrah after commencing its tawaf, unless he brought a sacrificial animal (hady) with him. 2. Another view: His Hajj is valid, and he becomes a qarin (one performing Hajj al-Qiran) and must offer a damm. This is the view of the Malikis and was chosen by some Hanbalis, such as Shaykh Abdullah ibn Aqil. Some of them restricted this to one who forgot or was ignorant, and he must offer a damm for abandoning the shaving or shortening of hair. 3. Shaykh Ibn 'Uthaymeen: He held the view that his Hajj is valid, and he remains a mutamatti' according to his intention. He must offer a fidyah (ransom, a sheep) for abandoning one of the obligatory acts of 'Umrah, which is shaving or shortening the hair.
