Good deed #494 – Approach wives after they purified from menstruation

{They ask thee concerning women’s courses. Say: They are a hurt and pollution: So keep away from women in their courses, and do not approach them until they are clean. But when they have purified themselves, ye may approach them as ordained for you by Allah for Allah loves those who turn to Him constantly and He loves those who keep themselves pure and clean.}[7]
[Al-Baqarah: 222]

Whoever has intercourse with a woman during her period, or sodomizes a woman, or who goes to a fortuneteller and believes him, has committed unbelief (if he considers any of these acts permissible).
[Reported by Abu Dawud and Tirmidhi]

When the Prophet (pbuh) wants to do something with one of his wives during her menstrual period, he covers her vagina and does what he wants.
[Reported by Abu Dawud]
