Intercourse with the wife after the cessation of bleeding via tayammum (dry ablution)

Question:
He also asks and says: What is the ruling if a man has intercourse with his wife after one of the two types of bleeding has stopped from her, but she has not performed ghusl (the full ritual bath), yet he ordered her to perform tayammum (dry ablution with clean earth)?

Answer:
It is obligatory to perform ghusl (the full ritual bath) if she has access to water and is able to do so. It is obligatory to perform ghusl because Allah said, “Then when you have purified yourselves, you may approach them.” So she must purify herself with water after menstruation or after post-natal bleeding, and then he may approach her. However, if they are traveling, or if she is ill and unable to use water, or if water is unavailable, then tayammum (dry ablution with clean earth) takes its place. She performs tayammum after menstruation or after post-natal bleeding, and her husband may approach her, because it has purified her.
