What is the ruling for one who is unable to complete the sniffing of water and wiping the ear due to illness?

Question:
The questioner says: I suffer from inflammation in the nasal sinuses, so sometimes I am unable to get water into my nose. Is my wudu' (ablution) considered valid? Also, I am unable to wipe my ear for this reason.

Answer:
If the nose is harmed, and the doctor says that the nose is harmed by water, or that your ear is harmed, or that the organ is harmed, then keep water away from it and perform tayammum (dry ablution). You keep water away from it and perform tayammum in place of washing the organ, if there is no cast or bandage on it. But if there is a bandage on it, you wipe over the bandage that is on it, and that is sufficient.
As for if there is no instruction from the doctor that water harms the nose, then it is obligatory for you to sniff water to the extent of your ability.
You put water into your nose to the extent of your ability. Even if you do not exaggerate in drawing it in, if you feel something or pain, do not exaggerate in drawing it in. The important thing is that you put the water in and take it out. Yes.
