Sayyiduna Uthman bin Abu al-As (may Allah be pleased with him) narrates that during the period of nifas (postnatal bleeding), he would not go near his wives (for intercourse) for forty days. Abu Muhammad (may Allah have mercy on him) says: Abu Bakr Hadhli (may Allah have mercy on him) has narrated this report as musnad from Hasan Basri (may Allah have mercy on him).
