Sayyiduna Abu Hurayrah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Disease is not contagious, no owl is an evil omen, the month of Safar is not an evil omen, and the sick should not be brought to the healthy, so that the healthy may stay wherever he wishes." It was said: O Messenger of Allah (peace and blessings be upon him)! Why is that? He said: "It is a harm."
This is gharib (unusual) with this chain, if al-Raqashi preserved it accurately; and Allah knows best.
