Sayyidah Umm al-Fadl (may Allah be pleased with her) said: I saw the Messenger of Allah (peace and blessings be upon him) pray Maghrib, and he recited in it Wal-mursalati 'urfa, and that was the last prayer he (peace and blessings be upon him) prayed; after it he (peace and blessings be upon him) did not pray any prayer.
