Običaj pokazivanja krvave posteljine nakon prve bračne noći

U mojoj kulturi, kada se neko ženi, parovima daju bijelu posteljinu koju koriste prve noći da pokaže krv djevice, a posteljina se mora vratiti rođacima. Znam da to nije islamsko. Ali da bih zaštitio čast moje žene, da li bi bilo prikladno da ubodem prst i stavim malo krvi na posteljinu samo da zaštitim svoju ženu od uznemiravanja?

QUESTION:
In my culture when someone get married they give the couples a white bedsheet to use on their first night to wipe the blood of the virgin, and the bedsheet has to be returned to the relatives. I know it’s not islamic to do so. But to protect my wife’s honor, would it be appropriate to prick my finger and put some blood on the bedsheet just to protect my wife from harassment.
