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