Imam Ali (AS) said, People are made deficient and flawed, except those whom Allah, the Glorified, protects. The questioner among them aims to embarrass and confuse while the answerer creates trouble. It is not long until the one who has the best views among them is turned away from his good opinion by pleasure or displeasure, and at any moment the most strong-willed among them will get affected by a single glance or transformed by a single expression.
