Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) says that the Prophet (peace and blessings be upon him) said: "The curse of Allah is upon the one who wrongfully takes as patrons those who are not his own, the one who seizes land, the one who leads a blind man astray from the road, the one who curses his parents, the one who slaughters for other than Allah, the one who commits bestiality with an animal, and the one who does the deed of the people of Lut; upon him is the curse of Allah three times."
