The requirement of wudhu for tawaf is one of the most discussed issues in Haji fiqh, with significant practical implications, especially during the intense crowding of Haji season when maintaining ablution can be extremely difficult. The three schools — Maliki, Shafi'i, and Hanbali (in the well-known position) — hold that ritual purity (taharah) is a condition (shart) for the validity of tawaf, meaning tawaf performed without wudhu would need to be repeated. Their primary evidence is the hadith narrated by Ibn Abbas that 'Tawaf around the House is like shalat, except that you may speak during it,' and Nabi's own consistent practice of performing wudhu before tawaf.
The Hanafi school takes a notable middle position: wudhu for tawaf is wajib (wajib) but not a condition of validity (shart). This means that if someone performs tawaf without wudhu, the tawaf itself is valid, but the person must pay a penalty (dam — sacrificing a sheep) for omitting the wajib act. If wudhu was lost during tawaf, the jamaah haji may perform wudhu and resume from where they left off. This position provides practical relief for jamaah haji who struggle to maintain ablution in the extreme crowds.
A third scholarly position, advocated by the great Hanbali jurist Ibn Taymiyyah and supported by some contemporary scholars, holds that wudhu for tawaf is strongly sunnah (mustahab) but not wajib. Ibn Taymiyyah argued that the hadith comparing tawaf to shalat is not authentically traceable to Nabi as a statement (marfu') but is rather a statement of Ibn Abbas himself (mawquf), and that Al-Al-Quran does not stipulate purity for tawaf. This position, while a minority view, is significant and has been adopted by some fatwa bodies for cases of genuine hardship.
