Ibn ul-Qayyim رحمه الله تعالى mentioned a statement attributed to the Salaf in origin:

A Shaytaan met another Shaytaan and said to him: “Why am I seeing you so thin & skinny?”

So he replied: “I am with a man who upon eating always mentions the name of Allah so I am unable to eat with him. When he drinks he mentions the name of Allah so I am unable to drink with him. When he enters his home he mentions the name of Allah so I (am unable to enter and instead l) have to sleep outside the house”.

So the first Shaytaan said: “I am with a man who upon eating never mentions the name of Allah so I eat with him. When he drinks he never mentions the name of Allah, so I drink with him. When he enters his home he never mentions the name of Allah so I enter with him. When he has intercourse with his wife he never mentions the name of Allah so I have intercourse with her too alongside him”.

عدة الصابرين ص٤٧
Iddat-asSaabireen, p:47

[Never mentions the name of Allah upon intercourse – i.e. does not say the prescribed du’a mentioned in Saheeh al-Bukhary & Saheeh Muslim: (In the name of Allah, O’ Allah, keep the devil away from us and keep the devil away from what you have blessed us with).
