He came to Jeddah intending to perform 'Umrah after finishing his work, so should he enter the state of ihram from the miqat when he passes it, or after finishing his work?

Question:
May Allah reward you with good. He asks: Is it permissible for a resident of Najran to enter the state of ihram for 'Umrah from Jeddah, on the grounds that he does not intend to perform 'Umrah until he finishes the mission he was assigned, or is it obligatory for him to go out to the miqat? He notes that the time was ample, a full day. We direct you to do so. May Allah reward you with good.

Answer:
If he came to Jeddah with the intention of 'Umrah, but wants to do a job he was assigned before performing 'Umrah, he must enter the state of ihram from the miqat he passes on his way. This is based on the saying of the Messenger (peace and blessings be upon him) when he designated the miqats: "They are for Hajj or 'Umrah." It is obligatory for him to enter the state of ihram from the miqat and perform the work in Jeddah while in the state of ihram.
Then, when he is done, he goes and performs the 'Umrah. Or he starts with the 'Umrah first. So, once he is finished with it, he goes to his work. The important thing is that he must enter the state of ihram from the miqat. However, if he came from the direction of his hometown without intending to perform 'Umrah, but rather saying, "If I am able to perform 'Umrah, I will do it; otherwise, it is not obligatory," then he enters the state of ihram from the place where he intends to perform 'Umrah, whether from Jeddah or elsewhere, from the place where he intends to perform 'Umrah and resolves to do so, because that is his miqat. This is based on the saying of the Messenger (peace and blessings be upon him): meaning, from where he intended the ritual, he enters the state of ihram from where he intended the ritual. Yes.
