They used the name of Islam to alter Islamic teachings and Islamic spirit. In the second dream, he saw (in the 6th year of Hijra) himself together with his followers entering Ka'bah. It was a time when, by worldly reasoning, he had no chance of doing so. Within less than 2 years, this dream became a reality. This type of inspiration still continues. The Holy Prophet said, "There is no prophethood after me except the good tidings".

He was asked, "And what are the good tidings, O Messenger of Allah?" He said, "Good dreams or true dreams". But the difference between a dream of a Prophet or Imam and that of others is that a Prophet or an Imam appointed by Allah never sees a false dream; whatever he dreams is a message or command from Allah; while other people's dreams are more often than not false, caused by physiological or psychological reasons.

2.Prophetic Inspirations: these inspired thoughts may be accompanied with clear words or may be in the form of a thought without words. The Qur'an says, "He (i.e. the Prophet) does not speak of his own desire, it is nothing but a revelation revealed". (53:3-4). By the authority of these verses of Qur'an even the traditions of the Holy Prophet are treated as revelation. Their words are not from Allah; but the idea is.

FROM BEHIND A CURTAIN The revelations, which are sent "from behind a curtain", are, also, of many kinds; 1.The first is like hearing some low murmuring sounds (like buzzing of bees) and knowing the interpretation. 2.The second is like hearing high-pitched sounds and knowing the interpretation. 3.The third is hearing the sound from a material object. The first call to the Prophet Musa (a.s) is one example. He was astonished to see a bush burning and yet remaining unconsumed by fire.

As he turned aside, gazing at a sight so unique, he received an authoritative call from God, calling him to prophethood. Another example is of our Prophet (s.a.w) when he ascended to the heavens in mi'raj. He, at last, arrived at a sublime place where neither any prophet nor any angel had ever reached. He saw a curtain of light, and then heard a voice from it. 4.The fourth type of this revelation is hearing the voice of an angel without seeing him.

It should be mentioned here that this fourth type of revelation "from behind a curtain" is not reserved for the prophets. Other chosen people also may be honored by such angelic conversations. They are called "al-muhaddath" (المحدّث) i.e. the one with whom the angels talk.
