Allah said:

﴿تِلْكَ حُدُودُ اللَّهِ فَلاَ تَعْتَدُوهَا وَمَن يَتَعَدَّ حُدُودَ اللَّهِ فَأُوْلَـئِكَ هُمُ الظَّـلِمُونَ﴾

(These are the limits ordained by Allah, so do not transgress them. And whoever transgresses the limits ordained by Allah, then such are the wrongdoers.)

This means that the laws that Allah has legislated are His set limits, so do not transgress them. An authentic Hadith states:

«إِنَّ اللهَ حَدَّ حُدُودًا فَلَا تَعْتَدُوهَا، وفَرَضَ فَرَائِضَ فَلَا تُضَيِّعُوهَا، وحَرَّمَ مَحَارِمَ فَلَا تَنْتَهِكُوهَا، وَسَكَتَ عَنْ أَشْيَاءَ رَحْمَةً لَكُمْ مِنْ غَيْرِ نِسْيَانٍ فَلَا تَسْأَلُوا عَنْهَا»

(Allah has set some limits, so do not transgress them; and commanded some commands, so do not ignore them; and made some things unlawful, so do not commit them. He has also left some matters (without rulings) as a mercy with you, not because He has forgotten them, so do not ask about them.)
