Ritual 312

If a pilgrim interrupts tawaf in order to obtain the merit of praying at the earliest time, or join congregational prayer, or perform a mustahab prayer, he must complete the tawaf from where he interrupted it after completing his prayer.

He should, as a matter of precaution, repeat tawaf after completing it, if the interruption was in the course of an obligatory tawaf and had occurred before completing the fourth round.
