Sura al-Nisāʾ 4:38

وَٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمْ رِئَآءَ ٱلنَّاسِ وَلَا يُؤْمِنُونَ بِٱللَّـهِ وَلَا بِٱلْيَوْمِ ٱلْأَخِرِ وَمَن يَكُنِ ٱلشَّيْطَٰنُ لَهُۥ قَرِينًا فَسَآءَ قَرِينًا

wa-lladhīna yunfiqūna amwālahum riʾāʾa l-nāsi wa-lā yuʾminūna billāhi wa-lā bil-yawmi l-akhiri wa-man yakuni l-shayṭānu lahu qarīnan fa-sāʾa qarīnan

Not those who spend of their substance, to be seen of men, but have no faith in Allah and the Last Day: If any take the Evil One for their intimate, what a dreadful intimate he is!
