Those were not causing failure [to Allah] on earth, nor did they (11:20)

﴿أُولَٰئِكَ لَمْ يَكُونُوا مُعْجِزِينَ فِي الْأَرْضِ وَمَا كَانَ لَهُم مِّن دُونِ اللَّهِ مِنْ أَوْلِيَاءَ ۘ يُضَاعَفُ لَهُمُ الْعَذَابُ ۚ مَا كَانُوا يَسْتَطِيعُونَ السَّمْعَ وَمَا كَانُوا يُبْصِرُونَ﴾
[ هود: 20]

11:20 Those were not causing failure [to Allah] on earth, nor did they have besides Allah any protectors. For them the punishment will be multiplied. They were not able to hear, nor did they see.

Such people cannot escape from Allah in this world if He wills to send down a punishment on them, and they have no protectors besides Allah who could stop the punishment of Allah from reaching them.
Their punishment on the Day of Judgement will be increased because they turned away themselves and turned others away from Allah’s path.
In this world, they were not able to hear the truth and guidance and accept it, and they did not see the signs of Allah in the universe in a way that was beneficial to them, because of their strong aversion to the truth.

By no means will they escape (from Allah's Torment) on earth, nor have they protectors besides Allah! Their torment will be doubled! They could not bear to hear (the preachers of the truth) and they used not to see (the truth because of their severe aversin, inspite of the fact that they had the sense of hearing and sight).
