Hadith e Qirtas is very famous in Bukhari and Muslim that holy Prophet asked for pen and paper to write something for his companion, so they won't astray from right path. Umar bin Khattab led that group of companions who refused to give it to the Prophet, they quarreled in front of Prophet and the Prophet sent them away from him.
In this narration they translated the word يَهْجُرُ as unconsciousness for the Prophet but actually it means someone talking about something while he is not to himself. This is a sever insult of the Prophet while the Prophet asked them to give him pen and paper, then the Prophet sent them out.
Here is the narration.
If the holy Prophet was unconsciousness, then why the Prophet (pbuh) said to them - go away from here, do not quarrel here?
There are so many verses in Quran always telling us that Obey the mesenger of Allah, anything Prophet gives you take it, if the Prophet stops you from anything, stop it. But we find something different in this companions.
