Some people are now venturing into manufacturing covid masks for selling and donating.

Answer

It is not permissible to emb a r k o n t h e m a s k manufacturing venture. These masks are used for a haraam purpose. These masks are the niqaabs of Iblees. The masks convey the belief of the wearer, namely, that he believes that disease is contagious by itself. It is also the effect of the ideology of atheists. This belief is in flagrant and diametric conflict with the declarat io n of Ras u lul lah (Sallallahu alayhi wasallam) who said: "There is no contagion in disease." The wearer of the niqaab of Iblees indicates his rejection of Rasulullah's categorical refutation of the contagion satanism.

Furthermore, it is haraam to wear any form of facecovering during Salaat. The Sahaabah would harshly rip off face-coverings from people during Salaat. Also, innumerable kuffaar medical experts have presented their scientific proofs for the harmful effects of wearing masks and constantly inhaling filthy air which is meant to be exhaled and expelled from the body. It is unnatural to wear these niqaabs of Iblees.

is permissible. However, if it has become customary such as Christmas day, then it will not be permissible. Eid cards are haraam.
