The miracles of the prophets before Mohammad (AS) were in a material state or manner, such as raising a dead body, or making a baby to speak in the cradle, or curing a deaf or blind. All such miracles had a material source and bed that could be felt or sensed. But as for the HOLY QURÄN, and its noble and amazing language, which is composed of the ordinary alphabetical letters, and goes so deep into the hearts and minds, making thought and wisdom to bow themselves in this respect, is something that should be considered a little deeper, and with more care.
