The basic principle is that slaughter, if it is with regard to something that it is not permissible to slaughter, represents wrongdoing, because wrongdoing is indicative of doing something inappropriate. This dream indicates that the slaughterer is calling the victim to misguidance.
Aman said to Ibn Sireen: I dreamt that I killed a boy and roasted him.
He said: You are going to commit wrongdoing towards this boy by calling him to something Haraam and he will obey you in that.If a person dreams that he ate some of his flesh that was cooked, he will get something good from him.
A man said to Ibn Sireen: I dreamt that I slaughtered my sister. He said: You have cut off ties with her.
A man said: I dreamt that a man slaughtered his wife. He said: This man should have come yesterday from a journey and had intercourse with his wife.
And that is what happened.If the dreamer sees a ruler killing a man and putting him on the neckof the dreamer without his head, this means that the ruler is wrong that one who was killed until he made him poor, then he will ask the one who is carrying him to pay some penalties which will be more or less according to how heavy or light the slain person is.
Moreover, if the slain person is recognized, then he is the one who will be wronged; if he is not known and he is an old man, the dreamer will be asked to paythe penalty of behalf of a friend; if (the slain person) is a young man, he will be asked to pay a penalty of behalf of an enemy. If the slain person still has a head, he will not be asked to pay a penalty.
Slaughter with something other than the correct tool is indicative of being appointed as a judge, because the Prophet (peace be upon him) said:“Whoever is appointed as a judge has been slaughtered without a knife.”A king dreamt that he slaughtered someone with a pen. Shahabuddin said to him: you will make him a judge.
And he appointed him as a judge.Slaughtering a child is indicative of fulfilling vows and of glory and status, because of the story of Isma’eel (May Allah be please with him). He said: If a person dreams that he slaughtered his son, that is indicative of fulfilling vows or going for Hajj, or it may mean that he will arrange his son’s marriage, upholdties of kinship and render back trusts.
