The ruling on one who does not spend the night at Muzdalifah due to the lack of space

Question:
The first question says: This questioner did not sleep at Muzdalifah because there was no space, so what is the ruling in that?

Answer:
By the Sunnah, may Allah have mercy on him, and whoever prays and sends blessings upon the Messenger of Allah (peace and blessings be upon him), if you were eager and sought [a place] but did not find one, then you owe nothing. This requires care and drawing near to Allah (Mighty and Majestic); it is not an easy matter. So if the pilgrim is unable to find a place in Mina or Muzdalifah, he owes nothing. As for 'Arafah, no, 'Arafah is necessary; whoever does not find a place in it has no Hajj. As for Muzdalifah and Mina, the correct view is that spending the night in them is obligatory for one who is able to do so, and for one who is unable, he owes nothing. This is if it is valid and he fears Allah in that. Yes.
