Are non-Muslims najis?

The verse people ask about

The question usually comes from this verse, revealed about the pagan Arabs of Makkah:

The Hanafi, Maliki, Shafi'i and Hanbali schools all explain "unclean" here as impurity of belief, not of the body. A small minority view, found mainly outside the four Sunni schools, took it literally, but mainstream Sunni scholarship does not.

What the Prophet ﷺ actually did

• He hosted non-Muslim delegations in his mosque and let a prisoner, Thumamah ibn Uthal, stay tied to one of its pillars before he accepted Islam (Sahih al-Bukhari 462). If non-Muslims were physically najis, that would never happen in a place of prayer.
• He ate food offered by a Jewish woman and dealt with Jewish neighbours in Madinah in trade and daily life.
• The Quran itself allows the food of the People of the Book and marriage to their chaste women (Quran 5:5). Both involve close physical contact.

When Abu Hurayrah slipped away because he was in a state of janabah, the Prophet ﷺ told him, "A believer never becomes impure" (Sahih al-Bukhari 283). Scholars explain that the human body itself is pure; impurity is something on the body, like urine or blood, not the person.

What this means for converts

You don't need to wash after hugging your mum or shaking your colleague's hand. Their cooking is fine to eat as long as the ingredients are halal. See Can I eat food my non-Muslim mom cooked? You can live with non-Muslim flatmates and share a kitchen. See Can I share a dorm room with a non-Muslim? And physical warmth with your family is part of honouring them. See Can I still hug my non-Muslim parents after becoming Muslim?

Where the real rules are

The only purity issues are specific substances: if someone's hand has wine, pork grease or urine on it, that substance is najis, the same as if a Muslim's hand did. Wash it off and carry on. Also, Makkah's sacred mosque is the place the verse restricts, not your living room or a local mosque visit.
