Article 257- The second act of obligatory acts of Hajj is Wuquf in Arafat. “Arafat” is a desert about 20 km from Mecca which has became semi-treed today and it is obligatory for Hajjis to say the noon of the ninth day of Dhu’l-Hijjah in that place.
Article 258- It is precaution to remain from the beginning of the noon of the ninth day until the sunset in there, afoot or ride, moving or sitting, awake or partly sleep, and it is Mustahab to pray and notice to the pure essence of Allah and asking forgiveness from him in that time, and the superiority of praying in that place and time is unexampled.
Article 259- Wuquf in Arafat is worship and should be performed with intention of closeness to Allah, and its intention has no specific statement and having the intention of performing that in the heart is enough.
Article 260- If a person leaves Arafat before sunset, if it has been performed because of forgetfulness or ignorance about the matter then there is nothing on him, but if has been done deliberately, then this person should sacrifice a camel in Mena (and if he/she cannot sacrifice a camel, then he/she should perform eighteen days of fasting) and his/her Hajj is correct anyway.
Article 261- Whenever a person returns to Arafat before the sunset and stay until sunset in there and then leaves the place, there is no atonement on him in this case.
Article 262- Although staying in Arafat is obligatory in all the time that has been mentioned before and renouncing it is a sin, but it is not one of essentials of Hajj, and the pillar is staying for a while in there, it means that if a person stays a part of the time from noon until sunset in Arafat, then his/her Hajj is correct, but if he/she renounces all the time then the Hajj is invalidated.
Article 263- It is obligatory for a person who has not been successful of completing Wuquf in Arafat from noon until sunset to stay some time in the night of Eid in that place; therefore, if a pilgrim reaches Arafat when people have left there, he/she stays a part of the night in there on the condition that he/she can reach Mash’ar al-Haraam before the dawn of the day of Eid and this is called “Emergency Wuquf of Arafat”.
And if this person couldn’t stay a part of night in Arafat, it is enough for him/her to perceive Wuquf a part of Wuquf in Mash’ar al-Haraam, which will be mentioned later, and his/her Hajj is correct in this way.
