Lesson

1. Physical Impurities: Two Categories

• Al-Najasah (Legally): Physical filth or contamination that affects the validity of prayer if it gets on a person's body, clothing, or place of prayer. • Categories: In Hanafi jurisprudence, physical filth (Najasah) is classified into two distinct legal classes based on its severity and the nature of its proof: ◦ Al-Najasah al-Ghalizah (Heavy Impurity): Severe filth established by absolute and decisive text. ◦ Al-Najasah al-Khafifah (Light Impurity): Mild filth where legal proofs allow some concession.

2. Heavy Impurities Part 1: Intoxicants and Secretions

Source text فَالْغَلِيظَةُ كَالْخَمْرِ، وَالدَّمِ الْمَسْفُوحِ، وَلَحْمِ الْمِيتَةِ وَإِهَابِهَا، وَبَوْلِ مَا لَا يُؤْكَلُ... • Core Examples of Heavy Impurity (Ghalizah): ◦ Wine (al-Khamr): Unrefined grape wine and all other liquid intoxicants. ◦ Flowing Blood (al-Dam al-Masfūh): Blood that runs or flows from a body. ◦ Flesh and Untanned Hide of a Carcass: The meat of any animal that died without proper Islamic slaughter, and its raw skin. ◦ Urine of Non-Edible Animals: The urine of any quadruped animal whose meat is haraam (prohibited) to eat (such as donkeys, cats, or dogs).

3. Heavy Impurities Part 2: Dogs, Predators, and Humans

Source text وَنَجْوِ الْكَلْبِ، وَجِيعِ السِّبَاعِ وَلُعَابِهَا، وَخرْءِ الدَّجَاجِ وَالْبَطِّ وَالْإِوَّزِّ... • Further Examples of Heavy Impurity: ◦ Dog Excrement (Najw al-Kalb): The feces of a dog. ◦ Excrement and Saliva of Predators: The dung and saliva (Lu'ab) of predatory beasts (such as lions, wolves, or leopards). ◦ Domestic Bird Droppings: The droppings of chickens (Dajaj), domestic ducks (al-Batt), and geese (al-Iwazz). ◦ Human Excretions: Anything that exits the human body and necessitates performing Wudu or Ghusl (such as human urine, feces, semen, flowing blood, or mouthful vomit).

4. Light Impurities (al-Najasah al-Khafifah)

Source text وَأَمَّا الْخَفِيفَةُ فَكَبَوْلِ الْفَرَسِ، وَكَذَا بَوْلُ مَا يُؤْكَلُ لَحْمُهُ، وَخرْءُ طَيْرٍ لَا يُؤْكَلُ • Examples of Light Impurity (Khafifah): ◦ Urine of a Horse: A horse's urine is classified as Light Impurity. ◦ Urine of Halal Animals: The urine of any quadruped whose meat is permissible to eat (such as cows, buffaloes, goats, sheep, and camels). ◦ Droppings of Non-Edible Birds: The droppings of birds of prey or non-edible birds (such as hawks, falcons, eagles, and crows).
