What is the ruling on the prayer of one who feels wind or other discharges exiting during ablution and prayer? Is it permissible for him to perform more than one prayer with a single ablution despite that? And how can he rid himself of this problem if it is caused by jinn?

Urinary incontinence and similar involuntary excretions should be disregarded. The person should pray according to their condition, even if fluid is discharged during prayer, due to Allah Almighty's saying: "And He has not placed upon you in religion any difficulty." The individual should wrap their private parts with tissues or similar items if they fear contaminating their body or clothes, then perform ablution and pray. This condition has no relation to jinn, and ritual purity must be renewed for each obligatory prayer.
