Who is the person whom Allah gave his signs, but he detached from them?

While reciting surat al-'Araaf I passed by these verses: > And recite to them, [O Muhammad], the news of *him to whom we gave [knowledge of] Our signs, but he detached himself from them*; so Satan pursued him, and he became of the deviators. **(175)**
> And if We had willed, we could have elevated him thereby, but he adhered [instead] to the earth and followed his own desire. So his example is like that of the dog: if you chase him, he pants, or if you leave him, he [still] pants. That is the example of the people who denied Our signs. So relate the stories that perhaps they will give thought. **(176)** My question is the person whom have been given the signs of Allah and who has detached himself from them a "Known " person our is this verse only a general example, what do tafseer books say about "him"?
