An-Nisa' 4:38

وَٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمْ رِئَآءَ ٱلنَّاسِ وَلَا يُؤْمِنُونَ بِٱللَّهِ وَلَا بِٱلْيَوْمِ ٱلْءَاخِرِ ۗ وَمَن يَكُنِ ٱلشَّيْطَٰنُ لَهُۥ قَرِينًۭا فَسَآءَ قَرِينًۭا

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!
