What is the revelation date of the verses concerning marriage and divorce?

There are numerous verses in the Qur'an concerning marriage and divorce, and the specific verse intended must be identified. It should be noted that the dating of the revelation of verses is often based on events rather than precise dates, as scholars have not been concerned with pinpointing the exact date of revelation except for verses related to abrogation (naskh). Other than that, they mention the story or incident in which the verse was revealed, as is the case in Surat Al-Talaq (The Divorce) and Surat Al-Baqarah (The Cow).
