IX/73: Oh Prophet! Strive against the disbelievers and the hypocrites! Be harsh with them. Their ultimate abode is hell, a hapless journey's end. LXIX/30-37: (It will be said)Take him and fetter him and expose him to hell fire. And then insert him in a chain whereof the length is seventy cubits. Lo! he used not to believe in Allah the tremendous, and urged not on the feeding of the wretched. Therefore hath he no lover hear this day nor any food save filth which none but sinners eat. Here we get a description of how to punish Non Muslims. This is in practice even today in Islamic countries. In fact, the Sikh Gurus and their families were tortured by muslims as prescribed in the Quran. For example, Sikh guru Tegh Bahadur on refusing to accept Islam, was brought to the prison in a cage like he was a wild animal. Three of his disciples were murdered in front of him. One of them was Bhai Mati Das. He was sawed alive. The other was wrapped up in cotton and burnt alive. Bhai Dyala, the third one, was boiled alive. Guru Tegh Bahadur himself was brutally tortured and killed in a similar fashion. We see further support of these types of torments in the verses below. XLIV/43-50: LO! the tree of Zaqqum (The tree that grows in the heart of hell bearing fruits like devil's heads) - the food of the sinner. Like molten brass, it seetheth in their bellies as the seething of boiling water. (And it will be said): Take him and drag him to the midst of hell, then pour upon his head the torment of boiling water. Saying: TASTE! LO! thou wast forsooth the mighty, the noble! Lo! this is that whereof ye used to doubt. IX/123: O ye who believe! Fight those of the disbelievers who are near to you and let them find harshness in you and know that Allah is with those who keep their duty (unto Him).
