Answer
(Fatwa: 290/194=L/1430)
In order to slaughter an animal (Qurbani), one should lay down the animal on ground facing Qiblah and recite:
انی وجھت وجھی للذی فطر السماوات والارض حنیفاً وما انا من المشرکین، ان صلاتی و نسکی ومحیای ومماتی للہ رب العالمین، لاشریک لہ وبذلک امرت وانا اول المسلمین، اللھم لک ومنک، بسم اللہ اللہ اکبر
And cut the throat of the animal i.e. the four arteries; first respiratory, second the food passage and two arteries on either sides of respiratory. If three of the arteries are cut then also the animal will be lawful for eating. One should recite the below dua after slaughtering:
اللھم تقبلہ منی کما تقلبت من حبیبک محمد وخلیلک ابراھیم علیھم السلام
(2) If the animal was slaughtered on the above-mentioned way, it will be considered halal and its meat will be lawful. But, if only two arteries were cut, then it will be considered carrion and unlawful to eat. Likewise, if recitation of Bismillah was deliberately left, then also the animal will be haram.
