On other hand Halala is also a temporary Nikah which is done to make a women halal for Nikah with his previous husband who divorced her. it is done by Hanfis in Subcontinent India Pakistan usually.
Islamically both the Mutah and Halala are haram according to Sahih Hadiths of Prophet Muhammad SAW. Lets see hadiths about both of these:
Hazrat Ali R.a said The Messenger of Allah had forbidden Mutah on the day of Khaybar and had forbidden the eating of the meat of domestic donkeys. Bukhari and Muslim
Prophet SAW said: ‘The Curse of Allah be upon the one who marries a divorced woman with the intention of making her lawful for her former husband, and upon the one for whom she is made lawful!’ Abu-Dawood Hadith 2071so in light of above hadiths its clear now that both Mutah and Halala are forbidden in Islam. people usually gets Halala done of their wives when they divorce their wives three times together in anger and then they want to get married again.
while giving three divorces together is also against the teachings of Rasool Allah SAW. at one time only one divorce can be given and even if someone gives three divorces at same times it will be considered one divorce not three Islamically. it gives time to both husband and wife to solve their dispute and need of Halala gets eliminated.
