Abandonment of prayer (salah)

۞ فَخَلَفَ مِنۢ بَعْدِهِمْ خَلْفٌ أَضَاعُوا۟ ٱلصَّلَوٰةَ وَٱتَّبَعُوا۟ ٱلشَّهَوَٰتِ ۖ فَسَوْفَ يَلْقَوْنَ غَيًّا

But there came after them successors [i.e., later generations] who neglected prayer and pursued desires; so they are going to meet evil -

فَلَا صَدَّقَ وَلَا صَلَّىٰ

And he [i.e., the disbeliever] had not believed, nor had he prayed.
