how to chech if the hadith is sahih???
wa alaikumsalam,
to check if the hadith is sahih or not, we must look for the person's name who responsible and admitted that Rasulullah S.A.W. did said the hadith by hearing it personally. These people normally were Rasulullah s.a.w's sahabahs and his family. We still can accept hadith that came from the trusted people during Rasulullah s.a.w era weather they hear it from the 2nd or 3rd parties as long as their names were stated means they were responsible about it.
Wassalaam.
