It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that Sayyiduna Umar (may Allah be pleased with him) delivered a sermon at the place of Jabiyah and said in it: The Messenger of Allah (peace and blessings be upon him) stood among us just as I am standing among you, and he (peace and blessings be upon him) said: I urge you to treat my companions well, and I advise you to show kindness to those who come after them, and then to those who come after them. After these times, lying will become widespread, to the extent that a man will begin to give testimony before he is asked for it. So whoever among you wishes to secure a place in the middle of Paradise, let him remain with the congregation, for the devil is with the solitary person, and he is farther from two people who are together. And none of you should be alone with a woman, for the third among them will be the devil. Also, when a man's good deed pleases him and his bad deed displeases him, then he is a believer.
