[But] Allah mocks them and prolongs them in their transgression [while] they (2:15)

﴿اللَّهُ يَسْتَهْزِئُ بِهِمْ وَيَمُدُّهُمْ فِي طُغْيَانِهِمْ يَعْمَهُونَ﴾
[ البقرة: 15]

2:15 [But] Allah mocks them and prolongs them in their transgression [while] they wander blindly.

Allah mocks the hypocrites for their mocking of the believers, and He will repay in equal measure for their behavior.
They are treated as believers in this world, but will be repaid for their lying and deception in the next life.
He allows them to become more and more lost and to do more and more wrong, so they remain confused and doubtful about the truth.

Allah mocks at them and gives them increase in their wrong-doings to wander blindly.
