Hadith 6012
`Umar reported God's messenger as saying, "Honour my companions, for they are the best of you; then those who follow them immediately; then those who follow them immediately. Then falsehood will appear so that a man will swear oaths without being asked to do so, and give testimony Without being asked to do so. He who would like to get to the very middle of paradise must adhere to the community, for the devil is with a single person, but farther away from two. A man must not be alone with a woman, for the devil makes a third along with them. He who is pleased by his good deeds and vexed by his evil gives various explanations of this, including unjustified pride, unjustified claims to nobility, acquisition of wealth, elaborate food and drink, neglect of religious duties. It is obviously some unsatisfactory characteristic which is intended.
