This blood is not the blood which remains inside the veins and capillary blood-vessels among its flesh that comes out from the animal's vessels after cutting them and pouring a great deal of blood from them.
The third exception is as follows :
All of these abovementioned things are disagreeable in man's nature and are the source of kinds of pollutions which cause some different damages.
Then, The Qur'an points to the fourth kind of these exceptions, and says :
From the point of ethical and spiritual views, this action is a sign of being aloof from Allah and from the school of theism both.
Thus, there are assigned two kinds of Islamic conditions for lawful slaughtering of an animal. Some of these conditions, such as cutting the four main blood-vessels of the animal and pouring forth its blood, have the aspect of hygiene, while some others, such as setting the animal toward the direction of the Ka'bah, reciting the holy phrase : 'Bis millah', and it being slaughtered by a Muslim, have spiritual aspects.
At the end of the verse, the Qur'an has made an exception, from the usage of these prohibited meats, those who are forced to eat them by necessity or because of lack of any other food in order to protect their lives, but not for pleasure nor more than the limits nor with the purpose of counting the divine unlawful things as lawful. It says :
In fact, these two conditions are for the sake that some people do not take this constrained circumstance as excuse for their transgression to the limits of the laws of Allah.
