Dear brother these haadith was naarated by Abu Dawud,but I am not sure is it really weak or authentic haadith. I have found it on many Islamic sites where this haadith been mentioned with talking about hijaab,so I am not really sure about its authenticy,SubhanAllah,Allah knows the best so I can not answer you.
Abu Dawud has collected about 50.000 haadith, he chose 4,800 for inclusion in his work, based on their superior authenticity.And Allah knows the best.
But if you really wish to know,Inshallah you can search by yourselfe and make sure which haadiths are sahih and which are not.
How would you for example give me prove that some haadith is authentic,or prove that ceratin fatwa from ceratin Schoolar is authenic??? For example,I always get back to the Quran,because if the Sunnah is not in accordance with Quran than that Sunnah is not authenic regarding fiqh issues.
