Nor are the living and the dead; God causes whomever He wills to hear. You cannot make hearers out of those in the graves.
وَما يَستَوِى الأَحياءُ وَلَا الأَموٰتُ إِنَّ اللَّهَ يُسمِعُ مَن يَشاءُ وَما أَنتَ بِمُسمِعٍ مَن فِى القُبورِ
wa maa yastawil ahyaaa’u wa lal amwaat; innal laaha yusmi’u mai yashaaa’u wa maaa anta bi musmi’im man fil quboor
