The emission of semen, without intercourse nullifies fasting and it is a sin, but you don’t have to pay the expatiation. It only nullifies your fasting as if you had something to eat or to drink and you have to make up for that day.

If one masturbates, with the intention of not ejaculating, but then he unintentionally ejaculates, does this break the fast and must he repeat the fast and is there a Kafarah?

Sheikh, when making wudhou if someone sniffs water in the nose and some amount of water goes down the throat.Does that invalidates the fast. If this happened to a person do they have to fast another day because they broke their fast. JazakAllah Khair.
