Explanation of the author's statement: "Then he inhales water"

The Shaykh : Now, "Then he inhales water", what is the meaning of inhaling water? Inhaling water is drawing water into the nose with the breath. Is it obligatory to blow out the water afterwards? It is not obligatory. They said that blowing out the water is a recommended practice (sunnah), but there is no doubt that the purification of the nose is not complete except by blowing it out after inhaling, so that what is in the nose of impurity is removed. However, the scholars mentioned that blowing out the water is a recommended practice (sunnah), and there is disagreement among them. But we are speaking about what is prescribed and the school of thought. Now, should one exaggerate in rinsing the mouth and inhaling water? The scholars said one should exaggerate, except if he is fasting, due to the saying of the Prophet (peace and blessings be upon him) to al-Qa'it ibn Shabrah: Likewise, one should not exaggerate in inhaling water if there are growths in the nasal cavities, because if he exaggerates in this state, the water may settle in these growths and then rot and become foul-smelling, or he may be harmed by it. This can happen to some people who have growths inside their nose; when they inhale water, it remains and settles between these growths, then rots, and it may have a bad smell. For such a person, it is sufficient to inhale water until it reaches the inside of the nostrils. Yes.
