I heard Messenger of Allah ﷺ saying, "The angels descend, the clouds and mention this or that matter decreed in the Heaven. The devils listen stealthily to such a matter, come down to inspire the soothsayers with it, and the latter would add to it one-hundred lies of their own." (Using translation from Bukhārī 3210)
"إِنَّ الْمَلائِكَةَ تَنْزلُ في الْعَنَانِ، وَهُو السَّحَابُ، فَتَذْكُرُ الأَمْرَ قُضِى في السَّمَاءِ، فَتَسْتَرقُ الشَّيَاطِينُ السَّمْعَ، فَتَسْمَعُهُ، فَتُوحيه إِلى الكُهَّان فيكذبون مَعَها مائة كذْبَةٍ مِنْ عِنْدِ أَنْفُسِهم".
