Ibn 'Abbas (May Allah be pleased with them) said

The Prophet (ﷺ) said, "He who narrates a dream which he has not seen will be put to trouble to join into a knot two barley seeds which he will not be able to do; and he who seeks to listen to the talk of a people (secretly) will have molten lead poured into his ears on the Day of Resurrection; and he who makes a picture (of people or other creatures with a soul, such as animals and insects) will be (severely punished), and he will be asked to infuse spirit therein, which he will not be able to do."
