i know there many sects in islam and only one of them will go to jannah as the prophet said صلى الله عليه وسلم , so is this stack exchange for everyone to post questions and have them answered, for example the shia, or just ahl al sunnah wal jamaa'ah? as far as i am concerned most the answers were sunnah based with the understanding of the righteous salaf, although i sadly saw people quoting one hadith and doing fatwa with it, even though there were other ahadith that would go exactly against it.
