Surah Al-'Ankabut — Ayah 23 (29:23)
وَٱلَّذِينَ كَفَرُواْ بِـَٔايَٰتِ ٱللَّهِ وَلِقَآئِهِۦٓ أُوْلَٰٓئِكَ يَئِسُواْ مِن رَّحۡمَتِي وَأُوْلَٰٓئِكَ لَهُمۡ عَذَابٌ أَلِيمٞ ٢٣
English translation (Saheeh International)
And the ones who disbelieve in the signs of Allāh and the meeting with Him - those have despaired of My mercy, and they will have a painful punishment.
Brief commentary
Those who disbelieved in the verses of Allah and meeting Him on the Day of Judgment, those have lost hope in My mercy, so they will never enter paradise due to their disbelief, and those will have a painful punishment that will await them in the afterlife.
