Concise Quran Commentary
When they are told not to ruin things on earth – through their rejection of the truth, their disobedience and so on – they deny doing so, claiming that they only correct things and put them right.
وَإِذَا قِيلَ لَهُمْ لَا تُفْسِدُوا۟ فِى ٱلْأَرْضِ قَالُوٓا۟ إِنَّمَا نَحْنُ مُصْلِحُونَ
When it is said to them, “Do not spread corruption in the land,” they say, “We are only reformers.”
