Silsilah as-Sahihah 741 — How men and women reply to permission

It is narrated from Sayyiduna Abdullah bin Zaid and Sayyiduna Abu Basheer Ansari (may Allah be pleased with them) that the Messenger of Allah (peace and blessings be upon him) was leading the companions in prayer one day in the valley of Batha. A woman wanted to pass in front, so the Prophet (peace and blessings be upon him) gestured to her to stop. Thus, she stepped back. When the Prophet (peace and blessings be upon him) finished the prayer, she passed in front.
