Surat Az-Zukhruf - سورة الزخرف

وَمَن يَعْشُ عَن ذِكْرِ الرَّحْمَٰنِ نُقَيِّضْ لَهُ شَيْطَانًا فَهُوَ لَهُ قَرِينٌ

Muhsin Khan: And whosoever turns away (blinds himself) from the remembrance of the Most Beneficent (Allah) (i.e. this Quran and worship of Allah), We appoint for him Shaitan (Satan - devil) to be a Qarin (an intimate companion) to him.
