Sayyiduna Ka'b bin Malik (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The believer is guileless and noble, while the wicked person is deceitful and base."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Yusuf bin al-Safr, who is a liar (kadhdhab).
