Sidi Hamou, the spirit of the slaughterhouse, is one of the leaders of the jinns of Morocco. Sometimes people refer to him as Sidi Mimoum El Djinnaoui which means 'Guest of God'. People feared this spirit so much they dared not do anything to offend him, so they would use this kind name to refer to the jinn just in case he was listening to their conversation.
Sidi Hammu likes red jawi and is particularly fond of blood. In fact, he lives around slaughterhouses and slaughters blocks, and is said to have a particularly intimate relationship with butchers. He has a number of followers among the Hamadsha, and is known to have sexual relations with some of the female devotees.
