﴿ إِنَّكَ لَا تُسْمِعُ ٱلْمَوْتَىٰ وَلَا تُسْمِعُ ٱلصُّمَّ ٱلدُّعَآءَ إِذَا وَلَّوْا۟ مُدْبِرِينَ ﴾

“[But,] verily, thou canst not make the dead hear: and [so, too,] thou canst not make the deaf [of heart] hear this call when they turn their backs [on thee] and go away,”

Indeed you cannot make the dead hear nor can you make the deaf hear the call when al-du‘ā’a idhā read by pronouncing both hamzas or by not pronouncing the second one eliding it with the yā’ they have turned their backs upon you;
