Seeing blood after having intercourse and purification from the menses

Q 4: A woman had her menses and after it ended and she found the sign of purity (on a white cloth), she performed Ghusl (ritual bath) and had sexual intercourse with her husband. After that, she started to bleed again. Did they have this sexual intercourse during Tuhr (period of ritual purity) or menstruation?

A: If the reality is as mentioned, this sexual intercourse happened while she was in a state of Taharah (ritual purification) and there is no harm on either of them. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
