Iblis places his throne upon water – Sahih Muslim
Sahih Muslim Book 039, Number 6755:
Jabir reported that Allah’s Messenger (may peace be upon him) said: Iblis places his throne upon water; he then sends detachments (for creating dissension) ; the nearer to him in tank are those who are most notorious in creating dissension. One of them comes and says: I did so and so. And he says: You have done nothing. Then one amongst them comes and says: I did not spare so and so until I sowed the seed of discord between a husband and a wife. The Satan goes near him and says: ‘You have done well. A’mash said: He then embraces him.
