question #1 Sahih al-Bukhari 227, Book 4, Hadith 93 : What steps should be taken to clean menstrual blood from clothing according to Islamic teachings?

A woman came to the Prophet (ﷺ) and said, “If anyone of us gets menses in her clothes then what should
she do?” He replied, “She should (take hold of the soiled place), rub it and put it in the water and rub it
in order to remove the traces of blood and then pour water over it. Then she can pray in it.”
