Silsilah as-Sahihah 616 — When did the Prophet perform Fajr prayer?

Lady Aisha (may Allah be pleased with her) says: We used to perform the Fajr prayer with the Messenger of Allah (peace and blessings be upon him), we had wrapped our shawls around us, and when we finished the prayer and returned, (due to the darkness) no one could recognize anyone's face.
