Placing the Forehead on a High Place by Mistake
Issue No.952- When a person places his forehead, by mistake, on a place that is higher or lower than four joined fingers compared to the place where his knees and toes rest, if it is so high that it could not be called a sajdah, he should raise his head and place it on a point whose height is less than four joined fingers. But, if the height is to the extent that it is still called a sajdah, it is obligatory to drag his forehead [while connected to the ground], to a place which is equal to four joined fingers or less [in height]. If this is not possible, the obligatory precaution is that he should complete his prayer and reoffer it.
