Messenger of Allah ﷺ said, "Anybody who believes in Allah and the Last Day should not harm his neighbor, and anybody who believes in Allah and the Last Day should entertain his guest generously and anybody who believes in Allah and the Last Day should talk what is good or keep quiet. (i.e. abstain from all kinds of evil and dirty talk).  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلاَ يُؤْذِ جَارَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ  

the Messenger of Allah ﷺ said, "Allah has decreed obligations, so do not neglect them; He has forbidden certain things, so do not violate them; He has set limits, so do not transgress them; and He has left some matters unspecified ˹intentionally˺, so do not delve into them.  

قَالَ رَسُولُ اللهِ ﷺ «إِنَّ اللهَ فَرَضَ فَرَائِضَ فَلَا تُضَيِّعُوهَا، وَنَهَى عَنْ أَشْيَاءَ فَلَا تَنْتَهِكُوهَا، وَحَدَّ حُدُودًا فَلَا تَعْتَدُوهَا، وَغَفَلَ عَنْ أَشْيَاءَ مِنْ غَيْرِ نِسْيَانٍ فَلَا تَبْحَثُوا عَنْهَا»
