The Day of Arafat (9th Dhul Hijjah) is the most important day of Hac and one of the most sacred days in Islam. Hz. Peygamber Muhammad said 'Hac is Arafat,' meaning that standing at Arafat is so central that missing it invalidates the entire Hac. It is a day of mass forgiveness, intense dua, and divine mercy. For non-hacilar, fasting on this day expiates the sins of the previous year and the coming year.
The unparalleled importance of the Day of Arafat in Islam is captured in a single profound hadith narrated by Abdur-Rahman ibn Ya'mar ad-Dili: Hz. Peygamber Muhammad (sallallahu aleyhi ve sellem) said, 'Al-Hajju Arafat' — 'Hac is Arafat' (reported by Abu Dawud, al-Tirmidhi, al-Nasa'i, and Ibn Majah, authenticated by al-Albani). This concise statement carries immense weight in Islamic jurisprudence. The scholars explain that Hz. Peygamber used this construction to indicate that the standing at Arafat is the greatest pillar of Hac, to the extent that the entire hac ibadeti is identified with it. If a haci performs every other ritual of Hac — the Tavaf, the Say, the stoning, the sacrifice — but misses the standing at Arafat during the prescribed time window, their Hac is invalid and must be repeated. Conversely, if a haci manages to reach Arafat for even a moment during the valid time (from after noon on the 9th until dawn of the 10th of Dhul Hijjah), the fundamental requirement of Hac is fulfilled, even if they miss other rites (which can be compensated through sacrifice). No other pillar of Hac is described in such absolute terms. This hadith has led many scholars to describe Arafat as the 'heart of Hac,' and the plain of Arafat as the most spiritually significant location a haci will visit during their entire Hac journey.
The plain of Arafat lies approximately 20 kilometers southeast of Mekke, outside the boundaries of the Haram. It is a vast, flat expanse surrounded by low hills, the most notable being Jabal ar-Rahmah (the Mount of Mercy), a small granite hill where tradition holds that Prophet Muhammad delivered his Farewell Sermon. The name 'Arafat' itself carries multiple etymological explanations rooted in the Arabic root 'a-r-f,' meaning to know or recognize. One tradition holds that it was at this location that Adam and Hawwa (Eve) recognized one another after being separated following their descent from Paradise. Another explanation is that Ibrahim came to know (ta'arafa) the rites of Hac shown to him by the angel Jibril at this place. Some scholars suggest the name derives from the fact that people come to know (ya'tarifu) their sins and seek forgiveness there. The boundaries of Arafat are clearly marked, and it is essential that hacilar position themselves within these boundaries for their standing to be valid. The valley of Uranah, which borders Arafat, is specifically excluded — Hz. Peygamber warned: 'I have stood here, but all of Arafat is a place of standing' (Sahih Muslim), while also noting that Uranah is not part of Arafat. Today, the Saudi authorities have erected signs and markers to help hacilar identify the boundaries, and modern tent camps accommodate the millions who gather there on the 9th of Dhul Hijjah.
The Day of Arafat follows a structured spiritual program that mirrors Hz. Peygamber's own practice during his Farewell Hac. Pilgrims typically arrive at Arafat after spending the night of the 8th in Mina, where they pray their five daily namazs shortened (qasr) as travelers. On the morning of the 9th, they proceed to Arafat after sunrise. The day begins with the Dhuhr and Asr namazs, which are combined and shortened at the time of Dhuhr (jam' taqdim), following the Sunnah. A sermon (khutbah) is delivered at the Masjid Namirah, which straddles the boundary of Arafat and Uranah, recalling Hz. Peygamber's historic Farewell Sermon in which he proclaimed the equality of all people, the sanctity of life and property, and the completion of the religion of Islam. After the namazs, the most important part of the day begins: the standing (wuquf). The haci faces the Qiblah, raises their hands, and engages in continuous, heartfelt dua from Dhuhr until sunset. Hz. Peygamber said: 'The best dua is the dua of the Day of Arafat, and the best thing that I and the prophets before me said is: La ilaha illallah wahdahu la sharika lah, lahul-mulku wa lahul-hamdu wa huwa ala kulli shay'in qadir' (There is no god but Allah alone, with no partner; to Him belongs sovereignty and praise, and He is over all things capable). Scholars emphasize that this is not a time for socializing, sleeping, or distraction — it is the single most precious window of dua in the entire Islamic calendar.
The Day of Arafat is described in multiple authentic hadiths as the day of greatest divine mercy and forgiveness. Hz. Peygamber Muhammad (sallallahu aleyhi ve sellem) said: 'There is no day on which Allah frees more people from the Hellfire than the Day of Arafat. He draws near, then He boasts about them to the angels and says: What do these people want?' (Sahih Muslim 1348). In another narration, Hz. Peygamber said: 'Allah descends to the lowest heaven on the afternoon of Arafat and boasts to the inhabitants of the heavens about the people of the earth, saying: Look at My servants, they have come to Me disheveled, dusty, and crying out from every deep valley. I call you to witness that I have forgiven them' (reported by Ibn Hibban and authenticated by al-Albani). These hadiths paint a vivid picture of divine generosity. The hacilar stand equal before their Lord — kings and paupers, scholars and laypeople, from every nation and tongue — in simple white garments that erase all worldly distinctions. The scene at Arafat is often described as a rehearsal for the Day of Judgment, when all of humanity will stand before Allah for reckoning. This imagery deepens the haci's consciousness of mortality, accountability, and the overwhelming mercy of Allah. Many hacilar describe the Day of Arafat as the most emotionally intense and spiritually transformative experience of their lives, a day when tears flow freely and hearts are laid bare before the Creator.
While those performing Hac are present at Arafat on the 9th of Dhul Hijjah, Muslims around the world who are not performing the hac ibadeti are strongly encouraged to fast on this day. Hz. Peygamber Muhammad (sallallahu aleyhi ve sellem) was asked about fasting on the Day of Arafat, and he replied: 'It expiates the sins of the previous year and the coming year' (Sahih Muslim 1162). This makes the fast of Arafat one of the most rewarding voluntary fasts in Islam, second only to the fast of Ashura in terms of the specific expiation mentioned in hadith. Scholars clarify that the sins expiated are minor sins (sagha'ir), while major sins require specific repentance (tawbah). The majority of scholars hold that hacilar themselves should not fast on the Day of Arafat, as Hz. Peygamber did not fast on this day during his Hac. The wisdom behind this is that fasting may weaken the haci and reduce their ability to engage in the extensive dua and worship that the day demands. Aisha reported that Hz. Peygamber was observed at Arafat and was not fasting, and a cup of milk was brought to him which he drank in view of the people to demonstrate that he was not fasting (Sahih al-Bukhari 1658). For non-hacilar, the Day of Arafat falls on the day before Eid al-Adha, and fasting on it connects the global Muslim community to the spiritual reality of Hac, allowing them to share in its blessings even from thousands of miles away. Many families make this a day of collective worship, gathering after iftar for namaz and dua, united in spirit with the hacilar standing at Arafat.
