How should a young man with a boil on his forehead prostrate when the doctor has put a plaster on it, and is it sufficient for him merely to touch the ground lightly with his head?

If the adhesive tape is on the forehead in such a way that prostration can be performed on a part of the forehead, then that is sufficient. If prostration on the forehead is not possible, then the worshipper should gesture with his head for prostration, bringing it as close to the ground as possible. It is not necessary to place a pillow for prostration if it is not already on the ground; gesturing is sufficient. Some scholars are of the opinion that it is obligatory to prostrate on the nose if prostration on the forehead is not possible.
