Why are you guys attacking her instead of telling her what is right this is not Muslim behavior @Life I'm sorry about them regarding your question the Quran is also followed by the Sunnah of the prophet their are different kinds of hadith with different strengths of the Hadith based on where it came from if a hadith is against the Quran then it's should not be used also their are culmaa that their job is to look at where the Hadith came from also their are many kinds of hadith their is Hadith quudsi which Allah told the prophet and their is Hadith of something the prophet said and then finally there is Hadith of someone mentioning what the prophet did also their are many things the sahaba say that people say it's Hadith even though Omar or Abu bakr said it so you have to be careful with reading where the Hadith came from I hope this helped you sis
But the Sunnah, the traditions, of the prophet comes from the Quran so how is it followed?
