The requirement of وضو for طواف is one of the most discussed issues in حج fiqh, with significant practical implications, especially during the intense crowding of حج 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 طواف, meaning طواف performed without وضو would need to be repeated. Their primary evidence is the hadith narrated by Ibn Abbas that 'طواف around the House is like نماز, except that you may speak during it,' and نبی کریم's own consistent practice of performing وضو before طواف.
The Hanafi school takes a notable middle position: وضو for طواف is wajib (واجب) but not a condition of validity (shart). This means that if someone performs طواف without وضو, the طواف itself is valid, but the person must pay a penalty (dam — sacrificing a sheep) for omitting the wajib act. If وضو was lost during طواف, the حاجی may perform وضو and resume from where they left off. This position provides practical relief for حجاج 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 وضو for طواف is strongly مستحب (mustahabb) but not واجب. Ibn Taymiyyah argued that the hadith comparing طواف to نماز is not authentically traceable to نبی کریم as a statement (marfu') but is rather a statement of Ibn Abbas himself (mawquf), and that قرآن مجید does not stipulate purity for طواف. This position, while a minority view, is significant and has been adopted by some fatwa bodies for cases of genuine hardship.
