Hac is referenced extensively in Kur'an-i Kerim, particularly in Surah Al-Baqarah (2:196-203), Surah Ali Imran (3:96-97), and Surah Al-Hac (22:26-37). Key hadith include Hz. Peygamber's farewell Hac description (Muslim 1218), 'Hac is Arafah' (Abu Dawud 1949), and 'An accepted Hac has no reward except Paradise' (Bukhari 1773).
The Kur'an establishes Hac as an obligation: 'And Hac to the House is a duty that mankind owes to Allah, for those who are able to make the journey' (3:97). Surah Al-Hac (Chapter 22) provides the most extensive Kur'anic treatment, including Ibrahim's proclamation of the hac ibadeti (22:27), the purpose of the sacrifice (22:36-37), and the symbols of Allah at the holy sites (22:32). Surah Al-Baqarah (2:196-203) contains detailed instructions on Hac rituals, including Ihram, the types of Hac, the days of Tashriq, and the remembrance at Muzdelife. Surah Al-Ma'idah (5:3) records the completion of Islam revealed on the Day of Arafah during Hz. Peygamber's farewell hac ibadeti.
The most comprehensive hadith on Hac procedure is the narration of Jabir ibn Abdullah describing Hz. Peygamber's farewell hac ibadeti in meticulous detail (Sahih Muslim, Hadith 1218). This single narration covers: Hz. Peygamber's Ihram at Dhul Hulayfah, his Tavaf and Say upon arrival, his journey to Mina on the 8th, Arafah on the 9th (including the Farewell Sermon), Muzdelife that night, the stoning and sacrifice on the 10th, and his general guidance to the companions throughout. Other key hadith include: 'Hac is Arafah' (Abu Dawud), establishing the standing at Arafah as the non-negotiable pillar; 'An Umre is an expiation for the sins between it and the next Umre, and an accepted Hac has no reward except Paradise' (Bukhari); and 'Whoever performs Hac and does not engage in obscenity or wickedness returns as the day his mother bore him' (Bukhari).
Numerous hadith emphasize the extraordinary spiritual rewards of Hac. Hz. Peygamber said: 'The performers of Hac and Umre are deputations of Allah. If they call Him, He answers them, and if they seek His forgiveness, He forgives them' (Ibn Majah). He also said: 'There is no day on which Allah frees more people from the Fire than the Day of Arafah' (Muslim). Regarding the spiritual equality of Hac: 'All mankind is from Adam and Eve; an Arab has no superiority over a non-Arab except by piety' (farewell sermon). And regarding the transformative power: 'Hac wipes out whatever came before it' (Muslim). These hadith collectively establish Hac as the most comprehensive act of worship in Islam — one that encompasses namaz, charity, self-denial, physical journey, communal solidarity, and complete surrender to Allah.
The great scholars of Islam have produced extensive commentary on the Hac verses and hadith. Ibn Kathir's tafsir (Kur'an commentary) provides detailed explanations of every Hac-related verse with supporting hadith. Al-Nawawi's commentary on Sahih Muslim includes exhaustive jurisprudential analysis of the farewell hac ibadeti narration. Ibn al-Qayyim's 'Zad al-Ma'ad' dedicates hundreds of pages to extracting practical and spiritual lessons from Hz. Peygamber's Hac. Al-Ghazali's 'Ihya Ulum al-Din' uniquely focuses on the inner dimensions and spiritual secrets of each ritual. These works remain the foundation of Hac scholarship and are essential reading for hacilar who want to understand the depth of what they are performing.
