Never proclaim about those who die consciously in the mystic way of Allah that they are dead. In essence, they live. But this fact cannot be perceived with ordinary eyes.
وَلَا تَقُولُوا لِمَنْ يُقْتَلُ فِي سَبِيلِ اللَّهِ أَمْوَاتٌ ۚ بَلْ أَحْيَاءٌ وَلَٰكِنْ لَا تَشْعُرُونَ
Wa laa taqooloo limai yuqtalu fee sabeelil laahi amwaat; bal ahyaaa'unw wa laakil laa tash'uroon
