وَمَا كَانَ رَبُّكَ مُهْلِكَ ٱلْقُرَىٰ حَتَّىٰ يَبْعَثَ فِىٓ أُمِّهَا رَسُولًۭا يَتْلُوا۟ عَلَيْهِمْ ءَايَٰتِنَا ۚ وَمَا كُنَّا مُهْلِكِى ٱلْقُرَىٰٓ إِلَّا وَأَهْلُهَا ظَٰلِمُونَ

Chapter: Following the Sunna of the Prophet (saws)
Narrated Abu Huraira:
The Prophet (ﷺ) said, "Leave me as I leave you, for the people who were before you were ruined because of their questions and their differences over their prophets. So, if I forbid you to do something, then keep away from it. And if I order you to do something, then do of it as much as you can."
