Surah Az-Zukhruf, ayah 36

43:36

وَمَن يَعۡشُ عَن ذِكۡرِ ٱلرَّحۡمَٰنِ نُقَيِّضۡ لَهُۥ شَيۡطَٰنٗا فَهُوَ لَهُۥ قَرِينٞ ٣٦

Waman ya'shu 'an dhikrir-rahmāni nuqayyid lahū shaytānan fahuwa lahū qarīn

And whoever is blinded from remembrance of the Most Merciful - We appoint for him a devil, and he is to him a companion.
