Does wiping the inner ear canal during ablution (wudu) or ritual bathing (ghusl) while fasting invalidate the fast, or does the one who says it invalidates the fast not mean the very entrance of the ear canal?

The intent of the fatwas is that the person performing ghusl or wudu should not pour water inside their ear canal, as it is harmful. What is required in ghusl is to completely cover the ear with water, while being careful not to let water enter the ear.

If a person performs wudu or ghusl, and water enters their ear unintentionally and without exaggeration, their fast is not invalidated according to the preponderant opinion. However, if they exaggerate until the water reaches their internal cavity, then those who consider water entering the ear to be an invalidator of the fast have differed in this case.

And those who say that the fast is broken by water entering the ear do not mean wiping or washing its exterior in wudu and ghusl, because this – if it is free from exaggeration – does not result in water entering the ear in a way that it reaches the internal cavity. As for water reaching the internal cavity without exaggeration, there is nothing wrong with it. And with exaggeration, there is a difference of opinion.
