Are the gases that exit during prayer—which may sometimes stop, or exit without sound—considered to be in the ruling of سلس ( سلس)?

The emission of gas invalidates ablution (wudu') and nullifies prayer (salat) if it occurs naturally. However, if it is continuous, such that it does not cease for a period allowing the individual to purify themselves and perform prayer, then its ruling is similar to that of urinary incontinence. In this case, one should perform ablution for prayer after its time has begun and then pray, and the emission of gas will not harm them. If there is a time when the emission of gas stops, then prayer should be delayed until that time, even if it means missing congregational prayer, unless there is a fear of the prayer's time expiring, in which case one must perform ablution and pray in any condition.
