﴿ وَإِذَا قِيلَ لَهُمْ لَا تُفْسِدُوا۟ فِى ٱلْأَرْضِ قَالُوٓا۟ إِنَّمَا نَحْنُ مُصْلِحُونَ ﴾

“And when they are told, "Do not spread corruption on earth," they answer, "We are but improving things!"”

(And when it is said unto them), i.e. the Jews (Make not mischief in the land) by preventing people from the Religion of Muhammad (pbuh) (they say: we are reformers only), we are reforming it through obedience.
