Allah Almighty says: "Behold! Verily on the friends of Allah there is no fear, nor shall they grieve; those who believe and guard against evil. For them are glad tidings, in the life of this world and in the Hereafter."
The Messenger of Allah (pbuh) explained the glad tidings of the life of this world to be dreams. He said it is: "the good dream that a Muslim sees or is seen for him"
The world of dreams is an amazing and intriguing one. The early scholar of Islam Ibn Qutaybah says: "There is nothing that people deal with from the different sciences that is more obscure, delicate, exalted, noble, difficult, and problematic than dreams, because they are a type of revelation and a kind of prophethood".
