The people who love one another for God's Sake Only

The Prophet(saw) said "Some of God's Servants who are neither prophets nor martyrs shall have on the Day of Judgement a position so close to God that prophets and martyrs would love to have." His companions said: "Messenger of God, will you please tell us who these people are." He said: "They are people who love one another for God's sake only. They have no relation of kinship or business interests with one another. By God, their faces are radiant with light, and they have light. They shall have no fear or sadness when other people are overtaken by fear and sadness." [Related by Abu Dawud]
