Hajj: Forgetting or Incorrectly Performing Tawaf al-Nisa
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 2058
If a person does not perform ṭawāf al‑nisāʾ correctly or forgets to perform it, in the event that he remembers this after a few days, goes back, and then performs it, it is valid. However, in the event that returning causes him excessive difficulty, he can appoint a representative [to perform it on his behalf].
