Al-Ankabut - 29:23

وَالَّذِينَ كَفَرُوا بِآيَاتِ اللَّهِ وَلِقَائِهِ أُوْلَئِكَ يَئِسُوا مِن رَّحْمَتِي وَأُوْلَئِكَ لَهُمْ عَذَابٌ أَلِيمٌ
[29:23]
And (as to) those who disbelieve in the communications of Allah and His meeting, they have despaired of My mercy, and these it is that shall have a painful punishment.
Those who reject the Signs of Allah and the Meeting with Him (in the Hereafter),- it is they who shall despair of My Mercy: it is they who will (suffer) a most grievous Penalty.
Those who disbelieve in the revelations of Allah and in (their) Meeting with Him, such have no hope of My mercy. For such there is a painful doom.
