Staying at Arafah means physical and mental presence in any part of Arafah, whether one is awake, asleep, riding, sitting, lying down, walking, and regardless of whether one is in a state of purity or not, e.g., a menstruating woman, or one giving birth, or a person having a wet dream. The scholars differ, however, about the position of one who faints and remains in a coma until he leaves Arafah. Abu Hanifah and Malik hold that the Hajj of such people is valid.
Ash-Shafi’i, Ahmad, Al-Hasan, Abu Thawr, Ishaq, and Ibn Al-Munzhir hold that such a person’s Hajj is invalid, because it is an essential part of Hajj, and a person in a coma cannot perform this or any other rites of Hajj.
After reporting the above hadith of Ibn Ya’mur, Tirmizhi remarks: “Sufyan Al-Thawri said that the knowledgeable Companions of the Prophet (peace be upon him) and others followed this hadith and held that a person failing to spend the day or a portion thereof at Arafah before the dawn of the 10th of Zhul-Hijjah, or arriving there after the sunrise, misses Hajj. Such a person should consider his present Hajj as an ‘Umrah, and must repeat it the next year. This is the opinion of Ash-Shafi’i, Ahmad, and others.
