Staying overnight outside Mina during the days of Hajj

Question:
May Allah reward you. In the second question, he says: Since we spent the nights that it is a recommended practice (sunnah) for the pilgrim to spend in Mina, following the action of the Prophet (peace and blessings be upon him), in a place about three kilometers from here, near King Faisal Bridge. I did not realize that we had stayed in an area outside Mina until after the 'Asr prayer on the Day of Tashriq. We asked to move to Mina, but they excused themselves on the grounds that we could not find a place for our truck due to the congestion. My sister was with me, and if she were not a woman whose presence is restricted, I would have stayed in Mina, because the tent is set up there. Please advise us: Is our Hajj valid? May Allah reward you. And what are the boundaries of the area?

Answer:
The Hajj is valid, but if you had a place in Mina and you left it, then you have committed a sin, as long as there is a place available in Mina. Why did you not move to it? However, if you were unable to move to it for reasons that prevented you from doing so, then you are not to blame.
