As for washing the face in general, without looking at the specification of the command in that, some of it is obligatory and some is not obligatory. As for the obligation, it is modesty before God to see you where He has forbidden you or to lose you where He commanded you. As for the Sunnah of it, modesty before God is to reveal your private parts, then God is better. To be ashamed of him, knowing that there is no part of you that he does not see of you, but his ruling on your actions from the point of view of you is obligated to what we have mentioned, and it has been reported, as well as looking at your wife’s private parts, even if that has been permitted to you, but using modesty in her is better and more important, so the obligation is waived . p>
