Hadith 3898
Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) narrates: (The Prophet Muhammad, peace and blessings be upon him) permitted menstruating women that when they experience menstruation, they may depart (before performing the Tawaf of the House of Allah). Sayyiduna Abdullah bin Umar (may Allah be pleased with them) says: Indeed, the Messenger of Allah granted these women this concession.
Hadith 3899
Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: Whoever performs Hajj should make the last act the Tawaf of the House (Ka'bah), except for menstruating women. The command for them is different. Allah's Messenger has granted them concession.
