Fatir 35:22

Wama yastawee al-ahyaowala al-amwatu inna Allaha yusmiAAu man yashaowama anta bimusmiAAin man fee alquboor

And not equal are the living and the dead. Indeed, Allāh causes to hear whom He wills, but you cannot make hear those in the graves.

And the living and the dead are not alike. Allah makes to hear whomsoever He wills. And you cannot make to hear those who are in the graves.
