sahih muslim + sahih bukhari
are the most trust hadith sources
partially because they never relied on single source of hadith
meaning the same hadith was told by more than one person or two
a group of people who were all tested for honesty
one time " muslim " the collector of hadith
travelled all the way long journey to see some one who claimed he had hadith he saw him fooling the cow to get into barn by pretending to have food and that was enough reason for muslim to refuse his hadith
saying just like you lied to this animal .. you could lie to me as well
