Is Abu Dawud's hadith regarding the permissibility of revealing the face and hands authentic or false, what is the meaning of a mursal hadith, and can it be acted upon despite the clear text in Surah Al-Ahzab, verse 59?

The hadith that the questioner likely refers to, regarding Asma bint Abi Bakr and her thin clothing, is a weak hadith. Even if it were authentic, it would still uphold the original ruling concerning the uncovering of the face and hands. However, the evidence indicating the obligation to cover them supersedes the original ruling, and what supersedes takes precedence over what upholds. Many authentic pieces of evidence have been established regarding the obligation to cover the face and hands, and these take precedence over any other evidence that permits their uncovering. As for the mursal hadith, it is a hadith narrated by a Tabi'i directly from the Prophet, peace and blessings be upon him, without mentioning the Companion. This type of hadith is considered weak by the majority of hadith scholars.
