Answered by Shaykh Yusuf Weltch
I know If a person is unable to control their wind for the duration of a Salah, they are excused. Is it necessary for the wind to come out at least once after the Azan of the new prayer is announced before proceeding to do wudu for it to be considered “unbreakable” from the said condition? Or, if one simply performs wudu as soon as the azan is announced, even if the wind has not yet blown, is that wudu considered “unbreakable”?
It is sometimes difficult to get through a whole wudu without stopping; I am restarting wudu up to ten times or more, which is exhausting and wastes a lot of water. Can I continue wudu even if something comes out in this case?
In the Name of Allah, the Most Merciful and Compassionate
Being Considered Excused (Ma’dhur)
In order to be considered excused, one must suffer from a condition that actually or effectively does not allow them to perform a valid ablution (wudu) and a whole prayer. [Tahtawi/Shurunbulali, Hashiyat Maraqi al-Falah]
Please see this link for full details.
The Excused Person
Once one is considered excused, the presence of their excuse (in this case passing wind) only breaks their wudu when that prayer time exits. Note that prayer time is what is important, not the call to prayer. Even though ideally, the call to prayer is done exactly when the prayer time enters, sometimes it is done late. [Ibid.]
Once you establish that you meet the conditions for the excused person, any passing of wind is not seen to immediately break your wudu, even if during the wudu, wind is passed, the wudu is still intact. [Ibid.]
Hope this helps
Allah knows best
