Dead body

89. The dead body of a human being is najis. Similarly the dead body of any animal whose blood gushes forth with force is najis, irrespective of whether it dies a natural death, or is killed in a manner other than that prescribed by Islam. As the blood o f a fish does not gush forth, its dead body is Pak, even if it dies in water.

90. Those parts of a dead body which do not contain life like, wool, hair, teeth, nails, bones and horns are Pak.

91. If flesh, or any other part which contains life, is cut off from the body of a living human being, or a living animal whose blood gushes forth, it will be najis.

92. Small pieces of skin which peel off from the lips, or other parts of the body, are Pak.

93. An egg from the body of a dead hen, is Pak, but its exterior must be washed.

94. If a lamb or a kid dies before it is able to graze, the rennet (cheese) found in its stomach is Pak, but its exterior should be washed with water.

95. The liquid medicines, perfumes, ghee, soap and wax polish which are imported, are Pak, if one is not sure of their being najis.

96. Fat, meat or hide of an animal, about which there is a probability that it may have been slaughtered according to the Islamic law, are Pak. However, if these things are obtained from a non-Muslim, or from a Muslim who himself obtained them from a non -Muslim, without investigating whether the animal was slaughtered according to Islamic law, it is haraam to eat that meat and fat, but namaz in that hide will be permissible.
But, if these things are obtained from Muslim Bazaar, or a Muslim, and it is not known that he got them from a non-Muslim, or if it is known that he got from a non-Muslim but there is a great probability that he has investigated about it being slaughtered according to Shariah, then eating such meat and fat is permissible.
