Missing one round of Tawaf

Q 8: If a pilgrim forgets to perform one of the rounds of Tawaf-ul-ifadah (final obligatory circumambulation around the Ka‘bah in Hajj) and does not realize it until leaving Al-Masjid Al-Haram (the Sacred Mosque in Makkah), what is the ruling on this? What should they do if they realize it after the minor Tahalul (partial ending of the state of Ihram through shaving the head and throwing pebbles at Jamarat-ul-‘Aqabah before performing Tawaf-ul-Ifadah), as this Tawaf is one of the two acts that achieve minor Tahalul?

A: If a pilgrim performs Tawaf-ul-Ifadah and forgets one of the rounds of Tawaf, and the period between the Tawaf and remembering is long, they should perform the whole Tawaf again. However, if the period is not long, they can make up for it by performing the round that they forgot.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
