It is narrated from Nafi' (may Allah have mercy on him) that Abdullah bin Abdullah bin Umar sent a messenger to Sayyidah Aisha (may Allah be pleased with her) to ask her whether a man can have intercourse with his wife while she is menstruating. She replied: She (the menstruating woman) should tie her lower garment tightly below, then the husband may have intercourse with her.
