What should I do when I sometimes experience flatulence during ablution (wudu') and prayer (salat)?

The emission of wind invalidates ablution (wudu') and necessitates its renewal. If the emission of wind stops for a time sufficient for purification and prayer before the prayer time expires, then one must wait for this interval, perform ablution, and pray. However, if it is continuous, then it is permissible to perform ablution at the beginning of the prayer time, and the emission of wind during prayer does not invalidate it, based on Allah's saying: "Allah intends for you ease" and "He has not placed upon you in religion any difficulty."
