He came to Jeddah not intending to do ‘umrah, then he decided to do ‘umrah and entered ihraam from Jeddah

This ihraam is valid, because you formed the intention for it from Jeddah, and you did not intend to do ‘umrah before that, so you do not have to offer any sacrifice for that. The basic principle concerning that is the hadeeth of Ibn ‘Abbaas (may Allaah be pleased with him): The Messenger of Allaah defined the meeqaat of the people of Madeenah as Dhu’l-Hulayfah; that of the people of Shaam (Syria) as al-Jahfah; that of the people of Najd as Qarn al-Manaazil; and that of the people of Yemen as Yalamlam. And he said: “And these meeqaats are for the people at those very places, and besides them for those who come thorough those places with the intention of performing Hajj and ‘Umrah; and whoever is living within these boundaries can enter ihraam from the place he starts and the same applies to the people of Makkah who may enter ihraam from there.” (Agreed upon). What is indicated by the general meaning of this hadeeth is that the one who wants to enter ihraam for ‘umrah may do so from Makkah is not as it appears to mean. There is evidence that the one who wants to enter ihraam for ‘umrah when he is in Makkah should enter ihraam from outside the sanctuary. It was narrated that ‘Aa’ishah (may Allaah be pleased with her) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) camped in al-Muhassab, then he called ‘Abd al-Rahmaan ibn Abi Bakr and said: “Take your sister out of the sanctuary and let her enter ihraam for ‘umrah and circumambulate the House, and I will wait for you here.” She said: So we went out, and I entered ihraam then I circumambulated the Ka’bah and did saa’i between al-Safa and al-Marwah, then we came to the Messenger of Allaah (peace and blessings of Allaah be upon him) in his camp in the middle of the night. He said: “Have you finished?’ I said: Yes. So he told his companions to move on, and went out and came to the Ka’bah and circumambulated it before Fajr prayer, then he set out for Madeenah. Agreed upon. 

And Allaah is the Source of strength. May Allaah send blessings and peace upon our Prophet Muhammad and his family and companions. End quote.
