5.Shaitans among humans.

In these verses of the Quran (2:14, 2:102, 6:112) the word shaitan refers to evil men. Whereas in the rest of the verses of the Quran it has the direct meaning.

The word shaitan wherever used either in the Quran or Hadiths should be taken in the direct context unless contradicting other verses of the Quran or the Hadiths of prophet Muhammad, or the basic concepts of Islam where it turns out to mean evil men. 

Similarly, when the structure of the verses of the Quran does not allow a direct meaning to the word it should be taken as meaning evil men. The above cited verses do not lead to a direct meaning of the word. 

 Prophet Muhammad (PBUH) said: When you are in the act of worship and if someone ventures to walk across distracting within the limits, in front stop him, in case he refuses stop him again, if he resists fight him, because he is a shaitan.

Narrator: Abu Huraira. 

Hadith Book: Bukhari 3275. 

Those who walk across people worshipping God are referred to as Shaitans by Prophet Muhammad (PBUH). Similarly evil men are referred to as shaitans in these verses.
