Is the hadith if we say ashhadu an lailaha illallahul……. after wudu then we can enter any gates of 8 of jannah. They say it’s from tirmidhi. Is the hadith authentic?

When I’ve to ask(dua)something or any good for a particul person & I ask it for all humanity then that specific person would be included in that,+ all humans.This is what I think but asking for specific only also comes in my mind though i know i can choose any option but want ur opinion as asking for everyone gives double benefit.
