The ruling concerning whoever left off spending the Night at Muzdalifah
Question :
What is the ruling concerning the Hajj pilgrim who left off spending the night in Muzdalifah on the night. preceding the 'Ed (10th of Thul-Hijjah)?
Answer:
Spending the night at Muzdalifah is Wajib (compulsory).
It is allowed for the weak to go ahead (to Mina) at the end of the night. Leaving it intentionally is a sin and necessitates a ransom (of atonement) [Fidyah] according to the majority of the people of knowledge. If someone did it out of ignorance, he is only required to offer a ransom (of atonement). If someone did so due to inability (to stay), the obligation is cancelled, like all other obligations (concerning the one who is unable to fulfill them). However, whoever arrived (at Muzdalifah) in time for the Fajr (Dawn) prayer, and remained after the prayer remembering Allâh, and then went forth (to Mina), he is accredited for that (with having fulfilled the obligation of staying at Muzdalifah).
