The ruling on adding to the tawaf (circumambulation of the Ka'bah) for one who doubts the number of circuits

Question:
The questioner asks: What is the ruling on adding to the tawaf if one forgets the number, and does it affect the 'Umrah (the lesser pilgrimage) or Hajj (the major pilgrimage)?

Answer:
Yes, if he doubts the number, he must build upon the lesser number with certainty. This is obligatory for him so that he exits the tawaf with certainty. If he doubts whether he performed six circuits or seven, he considers it six and performs the seventh, which is the one in doubt, so that he exits with certainty. As for adding intentionally, this is not permissible. Adding to a form of worship beyond the prescribed limit is not permissible, neither in tawaf nor in anything else.
