Sayyiduna Jabir bin Samurah (may Allah be pleased with him) narrates that Sayyiduna Umar bin Khattab (may Allah be pleased with him), while delivering a sermon at Jabiyah, said: The Messenger of Allah (peace and blessings be upon him) stood at a place like the one I am standing at and said: "Treat my companions well and deal with them kindly, then those who come after them, and then those who come after them. After that, there will come people who will swear oaths though they will not be asked to swear, and will bear witness though they will not be asked to bear witness. Whoever wants to attain a place in the middle of Paradise should adhere to the congregation, for indeed, the devil is with one person and is farther from two. No man should be alone with a (non-mahram) woman, for the third among them is the devil. A believer is one whose good deed pleases him and whose bad deed displeases him."
