The ruling on inserting a finger into the nose to perform istinshaq during wudu'

Question:
A woman says: Shaykh Salih, if a woman wants to perform istinshaq during wudu', she wets her fingers or one of her fingers with water and then inserts it into her nose. Is this istinshaq sufficient?

Answer:
This is not istinshaq; it is not sufficient for her to wet her finger and insert it into her nose. She must draw the water into the nose with her own effort, and then expel it with her own effort, so that the inside of the nose is reached by the water. It is not enough for her to insert her wet finger. Yes.
