It is narrated from Hazrat Yazid bin Abdullah that Hazrat Saeed bin Musayyib (may Allah have mercy on him) had a nosebleed during prayer, so he went into the chamber of Sayyida Umm Salama (may Allah be pleased with her), who was the wife of the Prophet (peace and blessings be upon him). Then water for ablution was brought, so he performed ablution and then returned and continued his prayer from where he had left off.
