What is the ruling regarding the waiting period (Iddah) for a woman divorced before consummation of the marriage?

Primary text

There is a consensus that the divorced woman who was not touched (consummated the marriage) has no waiting period incumbent upon her. The evidence for this is the verse, "O you who have believed, when you marry believing women and then divorce them before you have touched them, then there is not for you any prescribed waiting period to count concerning them" (Quran 33:49). This ruling is also derived from the rationale that the waiting period is required to ascertain the purity of the womb, which is certainly established in this case.
