Is water najis if a fly falls in it?
No, water does not become najis if a fly falls in it. The Prophet ﷺ actually told people what to do when a fly lands in a drink, which shows the drink stays pure. You can use the water for wudu, and you can drink it if you want to.
The hadith of the fly
The Prophet ﷺ said that if a fly falls into the drink of one of you, he should dip it all the way in and then take it out, because one of its wings carries disease and the other carries the cure (Sahih al-Bukhari 3320). Scholars point out a simple fiqh lesson here: if a fly made a drink impure, the Prophet ﷺ would not have said to dip it and carry on. Dipping it can even kill it, and the drink still stays pure.
You don't have to drink it, of course. Many people simply pour it away out of personal preference, and that's fine. The point is that it isn't najis.
Insects with no flowing blood
Most scholars from the four schools apply this to every small creature that has no flowing blood: flies, ants, bees, mosquitoes, beetles and similar insects. Even if one dies in water or food, it doesn't make it najis. Just take it out. The Shafi'i school has some detail about larger amounts, but in practice a fly or ant in your glass or in the wudu sink is no problem.
Water is pure by default. Allah describes rain as pure and purifying:
When water does become najis
- Real impurity changes it. If urine, blood or similar najis things fall into water and change its smell, colour or taste, it is no longer pure. See Is blood najis?
- Small amounts of water. Scholars differ on a small container where impurity falls in without a visible change; the Hanafi and Shafi'i schools are stricter here, while the Maliki view is more lenient.
- Insects are not in this group. A fly, ant or mosquito is not najis in itself.
Other animals around the house
The same easy-going approach applies to cats: water a cat drinks from stays pure, and many converts with pets find that a relief. See Are cats clean in Islam? If you notice you keep doubting whether water or surfaces are clean, read What is waswas and how do I deal with it?
- A fly falling into water or a drink doesn't make it najis.
- The hadith of the fly shows the drink stays pure.
- Insects without flowing blood don't make water impure, even if they die in it.
- Water only becomes najis through real impurity that changes it.
