Many groups leave Muzdalifah at the end of the night and before dawn because they have women and elderly people with them. Is it permissible for the strong to leave with them, or should they stay there until they have prayed Fajr?.
If the people are travelling in the same vehicle then they come under the same ruling. If they leave at the end of the night because of the weak and the women, then they may leave all together, because separating them will cause hardship for them, but Islam is a religion of ease. If this bus has sixty passengers, for example, and twenty of them are weak people who need to leave sooner so that they can stone the jamarah before dawn breaks, then it is permissible for the rest to do likewise, so these forty people may go with them on the bus because they are all one group, and separating them would cause them hardship.
