Hadith on Satan: The devil is most pleased when a husband and wife are separated
Jabir reported: The Messenger of Allah, peace and blessings be upon him, said, “Verily, Iblees placed his throne over the water and then he sends out his troops. The nearest to him are the greatest at causing tribulations. One of them says: I have done this and this. Iblees says: You have done nothing. Another says: I did not leave this person until I caused discord between him and his wife. Iblees says: You have done well.”

Let’s not please him rather please our Creator!
