I asked Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as) about a woman who married during her waiting period (iddah). Imam (as) said: "If she married during the waiting period after the death of her husband before the completion of four months and ten days, then she is not to be stoned, but she must be given one hundred lashes. However, if she married during the waiting period of a revocable divorce (where her husband could have taken her back), then she is subject to stoning. And if she married during the waiting period of an irrevocable divorce (where the husband had no right to return to her), then she is subjected to the punishment of an unmarried adulterer, which is lashes and not stoning. Moreover, if a Christian man commits fornication with a Muslim woman and, when apprehended for the execution of the punishment, he embraces Islam, the ruling for him is that he should be beaten until he dies. This is because Allah (swt), the Exalted, says: 'But when they saw Our punishment, they said: "We believe in Allah (swt) alone and disbelieve in what we used to associate with Him." But their faith was of no benefit to them when they saw Our punishment, which has been the way of Allah (swt) with His servants, and the disbelievers there and then were doomed to ruin.'" (Surah Ghafir 40:84-85)
