Hazrat Rubay’ (may Allah have mercy on him) says that I heard Hazrat Hudhayfah (may Allah be pleased with him) saying:“Islam, in the time of Hazrat Umar (may Allah be pleased with him), was like a man who is being welcomed and whose welcome increases day by day. But when Hazrat Umar (may Allah be pleased with him) was martyred, it became like a man who is going backwards and getting farther away day by day.”
