Imam Muslim reported on the authority of Jabir ibn `Abdullah, who stated that the Messenger of Allah (peace and blessings be upon him) said:
”Iblis (Satan) places his throne upon water, then sends his groups. The closest to him are those who (tempt people to) commit the most grievous of sins (fitnah). One of them would approach him and say: I did such-and-such. Iblis would ...reply: You have done nothing. Another would approach and say: I did not leave him (a man) until I caused him to leave his wife and for them to be separated. Iblis would bring him close to his throne and would say: How good you are!”
The first thing taught of magic was “..They learned from them the means to sow discord between man and wife.” [Quran Al Baqarah 2:102]
The Prophet (peace and blessings be upon him) said: "The most hateful permissible thing (al-Halal) in the sight of Allah is divorce." (Abu Dawud, Hadith 1863, Ibn Majah, Hadith 2008).
Prophet (peace and blessings of Allah be upon him) said: “Allah has forgiven for my ummah that which is whispered to them and which crosses their minds, so long as they do not act upon it or speak of it.” (Narrated by al-Bukhaari, 6664; Muslim, 127)
