The hell in Islam

According to Islam during the Yawn al-Akhina (the great inquest) all people will be revived and all of them will be judged. All people will be divided into two groups. One group will gather the inhabitants of paradise and the second one will gather the inhabitants of the hell.
The hell in Islam tradition is the eternal place for the sinners and infidels. God won't forgive polytheism. And the faith in any other god besides Allah is the sin in the Islam tradition. Other sins will be forgiven by Allah as he is very kind and wise.
There is the tree in the hell the roots of which reach the centre of the hell. The fruits of this tree are similar to the devil's heads. And the inhabitants of the hell will eat these fruits and drink the boiled water. They will get the sips of this water but won't have the ability to swallow it. And they will wear the clothes made of the fire. And all inhabitants will live feeling the sufferings because they lived their lives without honouring the real god.
The Koran criticises seriously all who mock at the message of the day of reckoning and the hell. It says that all of them will be punished for their sin deeds and that they didn't stop committing crimes and didn't start to honour Allah.
In fact the traditions of Islam, Judaism and Christianity are rather similar in the point of the other world and especially hell. All these religious describe it as physical as psychological suffering. All these religions consider people of other religions to be the sinners that will get to the hell.
