Surah 36. Yasin

58This is a rejoinder to the disbelievers, who slighted the Holy Prophet and his message by branding him a poet when he preached Tauhid and talked of the Hereafter, life-after-death, and Hell and Heaven. (For further explanation, see Ash-Shu'ara: 224-227 and the E.N.'s thereof).

59"Every living person" : Every person who is capable of thinking and understanding, who is not like a stone, which neither hears nor understands nor moves from its place* however rationally and sympathetically one may explain the distinction between the truth and falsehood and give admonition before him.
