Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) asked Sayyiduna Usamah bin Zaid (may Allah be pleased with him): What have you heard from the Messenger of Allah (peace and blessings of Allah be upon him) about the plague? He said that the Messenger of Allah (peace and blessings of Allah be upon him) said:“The plague is a punishment that was sent upon a group from the Children of Israel,”or he said,“upon those before you. So when you hear that it has broken out in a land, do not go there, and when it breaks out in a land where you are, do not flee from it.”Abu Nasr said: Do not leave with the intention of fleeing.
