This category includes exclusively urine of babies less than two years old who have not consumed any other food except his mother’s milk

Contaminants not included in the other two categories, such as tools or food products that are non-halal

This category includes also vomit, pus, blood, khamar, carrions, liquid and objects discharged from the orifices of humans or animals

Dogs and pigs (khinzir) including any liquid and objects discharged from their orifices, descendants and derivatives

Cleaning procedure

Remove the contaminant and sprinkle water over the contaminated area

Remove the contaminant and wash with running water until odor or visible traces of contaminant disappear

Remove the contaminant and wash seven times with running water, one of which shall be with water mixed with soil.

The first wash shall clear the najs. The water from first cleaning shall not remain behind and the successive wash shall be counted as the second wash.

The amount of soil used is just enough to make a suspension.
