Is it permissible to pray without prostrating, or to combine prayers and perform them at home, to avoid touching the nose to the ground or the prayer rug at work due to fears of coronavirus infection?

Prostration (sujud) is a pillar of prayer; the prayer is not valid without it, except for the incapable. It is performed on seven body parts: the forehead and nose, the two hands, the two knees, and the two feet. It is not permissible to delay the prayer beyond its prescribed time except for an excuse that allows for combining prayers. Precaution against contracting an illness is not considered an excuse for abandoning prostration or combining prayers. The worshipper can use their own prayer mat or clean plastic bags to pray on, then dispose of them afterward.
