I heard one of your lectures on YouTube which talks about leather being najis and it’s making me a little uncomfortable. You stated that najasat transfers with wetness. I have had leather couches and sofas for years, and I have taken ghusl/wudhu and then came and sat on them. So are all my salahs invalidated because I didn’t know that. Also I constantly touch the sofas while cleaning them wet, or when kids drop wet things on them, then we touch it and sit on it does that make us najis and we have to do ghusl afterwards? Of what if our wet hair touches the sofas after a shower? Or our wet hands after we wash our hands and come and sit? Does that need ghusl to be taken each time because we would be considered najis touching the leather? I do not know who the manufacturer is or where the leather came from, which animal or which country. Please advise what’s the ruling in this situation?

1- If you know that it is animal leather, and it was purchased from a non-Muslim company/market, and the leather is not from a cold blooded animal (like a snake or lizzard), then yes it is najes. Otherwise it’s not najes.

2- When the leather is najes, if you touch it with wet hands, your hands become najes. If your wet hair touches it, your hair becomes najes.

3- Now it doesn’t mean your ghusl is invalid and has to be redone. The ghusl itself is valid. But when you pray, you have to wash the area if your body that touched the sofa while wet.

4- If you did not know leather is Najes, and it’s not out of negligence that you didn’t know, meaning you made the effort to learn what is najes and what is not, but you simply never came to know that leather is najes, then in this case your previous prayers are all valid. But going forward, make sure if you touch the leather with wet hands, wash your hands before praying.
