﴿ زَعَمَ ٱلَّذِينَ كَفَرُوٓا۟ أَن لَّن يُبْعَثُوا۟ ۚ قُلْ بَلَىٰ وَرَبِّى لَتُبْعَثُنَّ ثُمَّ لَتُنَبَّؤُنَّ بِمَا عَمِلْتُمْ ۚ وَذَٰلِكَ عَلَى ٱللَّهِ يَسِيرٌۭ ﴾

“They who are bent on denying the truth claim that they will never be raised from the dead! Say: "Yea, by my Sustainer! Most surely will you be raised from the dead, and then, most surely, will you be made to understand what you did [in life]! For, easy is this for God!"”
