It is narrated from Hazrat Ibn Muhairiz (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Persia will fight the Muslims once or twice, then after that the kingdom of Persia will no longer exist. Rome is the one with horns; they are the people of the sea and the rocks. When one of their horns ends, another takes its place. In the last era, they will come to an end.
