 What you should do, standing near the dying person, Rasulullah sallallahu alaihi wa sallam said lakkinu mautakum bilaa ilaha ilallah, start saying slow audible voice the way that the person who's dying can just be able to listen to it, la ilaha illallah, la ilaha illallah, la ilaha illallah, la ilaha illallah. So the dying person, he would hear those words and he might say that in his on his tongue or in his heart, the best recitation you can do in front of the dying person is because in this they're both the things, one is forgiveness from Allah, asking forgiveness from Allah subhanahu wa ta'ala and the kalimah also comes la ilaha illallah.
