Sayyiduna al-Hasan bin Ali (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "On the Day of Resurrection, the people will be gathered barefoot and naked." A woman said: "O Messenger of Allah, then how will we see one another?" He (peace and blessings be upon him) said: "On that Day the eyes will be fixed (upward)." Then he (peace and blessings be upon him) raised his gaze to the sky. She said: "O Messenger of Allah, pray to Allah that He cover my nakedness." He (peace and blessings be upon him) said: "O Allah! Cover her nakedness."
