Is it true that when you are saying the Salat (i.e. Fajr, Zuhr, Asr, Maghrib, or Isha) and you want to break wind but you did not, that you have to perform Wudu again and repeat you Salat?
Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
Passing wind is among the nullifiers of Wudu. The Wudu nullifies when the wind actually passes. If one only intends to pass wind and actually did not do so, or one feels a need of its passing but he controls it then the Wudu is not nullified since the Wudu is nullified only by actually passing wind.
Allah knows best.
