In the name of ALLAH, the Entirely Merciful, the Extremely Merciful.
Jabir reported: The Messenger of Allah, peace and blessings be upon him, said, “Verily, Satan places his throne over the water and he sends out his troops. The closest to him in rank are the greatest at causing tribulations. One of them says: I have done this and this. Satan says: You have done nothing. Another one says: I did not leave this man alone until I separated him from his wife. Satan embraces him and he says: You have done well.”
