What is the legal ruling regarding the triple divorce that occurred, knowing that the first two divorces took place during a period of purity in which he had intercourse with her, and the third divorce took place during a period of purity in which he had intercourse with her, and it was later discovered that she was pregnant at that time, given the disagreement surrounding the occurrence of an innovative divorce (talaq bid'i)?

Divorce pronounced during menstruation or during a period of purity in which the wife was touched is valid and forbidden. This is the view of the majority of scholars, in contrast to Ibn Taymiyyah, who does not consider innovative divorce (talaq bid'i) to be effective, which includes divorce pronounced during a period of purity in which she was touched before her pregnancy became apparent. There is no blame upon someone who acts according to the opinion of some scholars in matters of disagreement, as long as he is reassured by it.
