those slain in Allah's cause are alive

وَلَا تَقُولُوا۟ لِمَن يُقْتَلُ فِى سَبِيلِ ٱللَّهِ أَمْوَٰتٌۢ ۚ بَلْ أَحْيَآءٌ وَلَـٰكِن لَّا تَشْعُرُونَ

Do not say that those who are killed in God’s cause are dead; they are alive, though you do not realize it.

وَلَا تَحْسَبَنَّ ٱلَّذِينَ قُتِلُوا۟ فِى سَبِيلِ ٱللَّهِ أَمْوَٰتًۢا ۚ بَلْ أَحْيَآءٌ عِندَ رَبِّهِمْ يُرْزَقُونَ

[Prophet], do not think of those who have been killed in God’s way as dead. They are alive with their Lord, well provided for,
