It is narrated from Sayyiduna Abu Musa (may Allah be pleased with him), he said: The Jews would sneeze in the presence of the Prophet (peace and blessings of Allah be upon him), hoping that the Prophet (peace and blessings of Allah be upon him) would say to them «يرحمكم الله» , but the Prophet (peace and blessings of Allah be upon him) would say: "May Allah guide you and set your affairs right."
