Musannaf Ibn Abi Shaybah 13650 — A woman whose menses begin before she

Al-Qasim bin Muhammad was asked about a woman who performed the Tawaf of the House on the Day of Sacrifice and then began menstruating before departing. He said: "May Allah have mercy on Sayyiduna Umar (may Allah be pleased with him). All the Companions say that she has finished, except Sayyiduna Umar; he says that her last act should be the Tawaf of the House."
