This is what Najis is according to Islam:

In Islamic law, najis (Arabic: نجس‎) are things or persons regarded as ritually unclean.[1] According to Shi'a Islam, there are two kinds of najis: the essential najis which can not be cleaned and the unessential najis which become najis while in contact with another najis.[1]

Contact with najis things brings a Muslim into a state of ritual impurity (najasat), which requires undergoing purification before performing religious duties, such as regular prayers.

Islamic law

According to the Shafi'i school of Sunni Islamic jurisprudence, as systematised by al-Nawawi in his book Minhadj, the following things are najis: wine and other spirituous drinks, dogs, swine, dead animals that were not ritually slaughtered, blood, excrements, and milk of animals whose meat Muslims are not allowed to eat. Spirituous drinks are not impure according to the Hanafi school, while living swine are not impure according to the Malikis.[1]
