Is it permissible to wear underwear beneath the ihram due to drops of urine or prostatic/pre-seminal fluid discharging after relieving oneself and during sleep?

What was mentioned is an excuse that permits wearing sewn garments to avoid the spread of impurity in clothes, if there is no alternative. However, it is more cautious to offer a fidya (expiatory payment), where one has the choice between feeding six poor people, giving each half a sa' (a measure of volume), or slaughtering a sheep, or fasting for three days.
