It is narrated from Sayyiduna Abu Tha'labah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The dearest of you to me and the closest of you to me in seating in the Hereafter are those of you who are best in character, and the most hateful of you to me and the farthest of you from me in the Hereafter are those of you who are worst in character: the chatterers, those who speak affectedly, and those who show off arrogance in knowledge."
