The Sirât Bridge
When mentioning the Sirât Bridge, we should not suppose that it is like bridges that we know. As a matter of fact, we say that it is necessary to pass the bridge of examination in order to pass the course.
Every student will pass the bridge of examination. We call it a bridge because all students have to pass it. However, an examination is in no way similar to a bridge. There are those who can pass the bridge of examination, and there are also those who cannot pass it and fall down. But this is unlike falling down into the sea from a bridge. Only those who have passed the bridge of examination know how it is. Likewise, everybody will have to pass the Sirât Bridge, and others, being unable to pass, will fall down into Hell. But this bridge, passing it or falling down into Hell, is not like worldly bridges or the bridge of examination. It has no aspects resembling them.
