There are lots of fake narrations made for Umar bin Khattab. We want to provide the proof of our claim. 

Please find this narration in Bukhari that Saitan tried his best on holy Prophet while he was praying. 

URDU TRANSLATION:

Please find the other narration in same chapter that Saitan runs away from Umar and changes his way from him.

URDU TRANSLATION:

We can imagine how these narrations were made for some people that Satan never leaves the holy prophet who is the head of prophet, closest creation near to Allah. Satan tries on him, even prophet is praying, while run away from Umar bin Khattab.

We believe , we have provided enough informations about Umar bin Khattab from Bukhari, now we move to our next topic about companions in Bukhari
