Limits of the Prophet's responsibility

وَلَوْ شَآءَ ٱللَّهُ مَآ أَشْرَكُوا۟ ۗ وَمَا جَعَلْنَـٰكَ عَلَيْهِمْ حَفِيظًا ۖ وَمَآ أَنتَ عَلَيْهِم بِوَكِيلٍ

But if Allāh had willed, they would not have associated. And We have not appointed you over them as a guardian, nor are you a manager over them.

قُلْ إِنَّمَآ أُنذِرُكُم بِٱلْوَحْىِ ۚ وَلَا يَسْمَعُ ٱلصُّمُّ ٱلدُّعَآءَ إِذَا مَا يُنذَرُونَ

Say, "I only warn you by revelation." But the deaf do not hear the call when they are warned.
