The Book Giving Description of the Day of Judgement, Paradise and Hell (Kitab Sifat Al-Qiyamah wa'l Janna wa'n-Nar)
Muslim :: Book 39 : Hadith 6757
Abdullah b. Mas'ud reported that Allah's Messenger (may peace be upon him) said: There is none amongst you with whom is not an attache from amongst the jinn (devil). They (the Companions) said: Allah's Messenger, with you too? Thereupon he said: Yes, but Allah helps me against him and so I am safe from his hand and he does not command me but for good.
