He could not spend the night in Muzdalifah due to its being overcrowded

Q 3: The huge crowding during Hajj last year did not allow some pilgrims to spend the night in Muzdalifah; it was difficult to reach it and some of them even lost their way. What should they do?

A: The obligation to spend the night in Muzdalifah is waived for whoever is unable to fulfill it due to crowding. As for those who lost their way and spent the night in another place, they must offer Dam (sacrificial animal offered as an atonement) because it was possible for them to ask for directions to go there. They acted negligently by not asking for directions.
