Ritual 308

If, without good reason, the pilgrim steps out of the course of tawaf, completing the fourth round, the tawaf is invalid and has to be repeated. If it was after the fourth round, tawaf, as a matter of precaution, must be completed and then repeated. However, if the tawaf was optional, he may complete the remaining rounds, provided that he does not break the sequence.
