Manners in Speech

A liar is a hypocrite When the Prophet was asked if it was possible for a believer to be a coward, he replied that it was. When asked whether a believer could possibly be miserly, he again replied in the affirmative. But when he was asked whether a believer could be a liar, he said that he could not. According to Hudhaifah, when anyone told a lie in the days of the Prophet, that was tantamount to being a hypocrite. “And now,” he remarked, “I hear all of you telling lies ten times a day.”
