وَمَا يَسْتَوِي الْأَحْيَاءُ وَلَا الْأَمْوَاتُ ۚ إِنَّ اللَّهَ يُسْمِعُ مَنْ يَشَاءُ ۖ وَمَا أَنْتَ بِمُسْمِعٍ مَنْ فِي الْقُبُورِ 22
Nor are alike those that are living and those that are dead. Allah can make any that He wills to hear; but thou canst not make those to hear who are (buried) in graves.
