Islam is a religion that not only cater for the soul and spirit of man but it is also concerned with his physical wellbeing and health. Only a healthy body with a spiritually sound soul can worship Allah diligently. From this view point, Islam came to prohibit some food for man and laid down strict rules to be followed in order to make hunted games and some other animals halaal (permissible to be eaten) to help him maintain good health and general wellbeing.
A number of conditions must be met for hunting wild animals, including the following:
1. The hunter must be sane and must have intended to carry out such act. Therefore, game hunted by a pagan or an insane person is not lawful (halaal).
2. The game must belong to the category of animals that cannot be easily slaughtered, as they tend to run away from humans. If, however, it can
be slaughtered, such as sheep and chicken, then it is not permissible to hunt them.
3. Hunting weapon must kill by virture of its sharpness, like an arrow or a bullet. Meat from animals that are killed by anything else by virtue of its weight, such as a rock, is not lawful for eating, unless one could slaughter the game before it dies.
4. The name of Allah must be pronounced when hunting weapon is discharged.
5. If the hunted game is still alive, it must be slaughtered straightaway.
6. Hunting is permitted in Islam only when necessary for food. Taking the life of an animal for sports, without intending to eat from it or otherwise benefit from it, is prohibited.
As for slaughtering the animal, it must be directed to Qibla and Allah's name must be mentioned before the animal is slaughtered, at best when the knife if just about descending on its throat. Allah the Almighty says;
)فَكُلُوا مِمَّا ذُكِرَ اسْمُ اللَّهِ عَلَيْهِ إِنْ كُنْتُمْ بِآَيَاتِهِ مُؤْمِنِينَ . وَمَا لَكُمْ أَلَّا تَأْكُلُوا مِمَّا ذُكِرَ اسْمُ اللَّهِ عَلَيْهِ وَقَدْ فَصَّلَ لَكُمْ مَا حَرَّمَ عَلَيْكُمْ إِلَّا مَا اضْطُرِرْتُمْ إِلَيْهِ وَإِنَّ كَثِيرًا لَيُضِلُّونَ بِأَهْوَائِهِمْ بِغَيْرِ عِلْمٍ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِالْمُعْتَدِينَ(
“So eat of that (meat) on which Allaah’s Name has been pronounced (while slaughtering the animal), if you are believers in His Ayaat (proofs, evidences, verses, lessons, signs, revelations, etc.) And why should you not eat of that (meat) on which Allaah’s Name has been pronounced (at the time of slaughtering the animal), while He has explained to you in detail what is forbidden to you, except under compulsion of necessity? And surely, many do lead (mankind) astray by their own desires through lack of knowledge. Certainly your Lord knows best the transgressors” (Q6:118-119)
)وَلَا تَأْكُلُوا مِمَّا لَمْ يُذْكَرِ اسْمُ اللَّهِ عَلَيْهِ وَإِنَّهُ لَفِسْقٌ وَإِنَّ الشَّيَاطِينَ لَيُوحُونَ إِلَى أَوْلِيَائِهِمْ لِيُجَادِلُوكُمْ وَإِنْ أَطَعْتُمُوهُمْ إِنَّكُمْ لَمُشْرِكُونَ(
“Eat not (O believers) of that (meat) on which Allah’s Name has not been pronounced (at the time of the slaughtering of the animal), for sure it is Fisq (a sin and disobedience of Allah). And certainly, the Shayaateen (devils) do inspire their friends (from mankind) to dispute with you, and if you obey them[by making Al‑Maytah (a dead animal) legal by eating it], then you would indeed be Mushrikoon (polytheists); [because they (devils and their friends) made lawful to you to eat that which Allah has made unlawful to eat and you obeyed them by considering it lawful to eat, and by doing so you worshipped them; and to worship others besides Allah is polytheism]” (Q6:121)
)حُرِّمَتْ عَلَيْكُمُ الْمَيْتَةُ وَالدَّمُ وَلَحْمُ الْخِنْزِيرِ وَمَا أُهِلَّ لِغَيْرِ اللَّهِ بِهِ وَالْمُنْخَنِقَةُ وَالْمَوْقُوذَةُ وَالْمُتَرَدِّيَةُ وَالنَّطِيحَةُ وَمَا أَكَلَ السَّبُعُ إِلَّا مَا ذَكَّيْتُمْ وَمَا ذُبِحَ عَلَى النُّصُبِ وَأَنْ تَسْتَقْسِمُوا بِالْأَزْلَامِ ذَلِكُمْ فِسْقٌ الْيَوْمَ يَئِسَ الَّذِينَ كَفَرُوا مِنْ دِينِكُمْ فَلَا تَخْشَوْهُمْ وَاخْشَوْنِ الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الْإِسْلَامَ دِينًا فَمَنِ اضْطُرَّ فِي مَخْمَصَةٍ غَيْرَ مُتَجَانِفٍ لِإِثْمٍ فَإِنَّ اللَّهَ غَفُورٌ رَحِيمٌ(
"Forbidden to you is that which dies of itself, and blood, and flesh of swine, and that on which any other name than that of Allah has been invoked, and the strangled (animal), and that beaten to death, and that killed by a fall, and that killed by goring with the horn, and that which wild beasts have eaten — except what you slaughter; and that which is sacrificed on stones set up (for idols), and that you seek to divide by arrows; that is a transgression..." )Q5:3).
The Prophet (peace be upon him) was narrated to have said, "Two kinds of dead meat and two kinds of blood have been permitted to us. The two kinds of dead Meat are fish and locusts, and the two kinds of blood are the liver and spleen" (Ibn Majah)
Firstly: Mentioning the name of Allah is a condition of meat being halaal (lawful and permissible to be eaten), and it is not excused by forgetfulness or ignorance, according to the most correct scholarly opinion.
Secondly: Meat slaughtered by one of the people of the Books (a Jew or a Christian) is permissible subject to two conditions: 1 – That the meat be slaughtered as a Muslim does it, by cutting the throat and esophagus and letting the blood flow. If the animal is killed by strangling or electric shock or drowning in water, its meat is not permissible. Similarly, if a Muslim does that, the meat is not permissible."
