It is narrated from Sayyiduna Rabah al-Lakhmi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Egypt will soon be conquered, so benefit from its good, but do not take it as a permanent home, for those who are drawn there are the shortest-lived of people."
