Urinary incontinent patients having to perform Wudu' for each Salah

Q: I had a hemorrhoid operation more than a year and a half ago. After this operation, I could no longer control the state of Taharah (ritual purification) regarding the passage of gases, urine and the like. This caused me grief and a difficulty to purify the parts which become wet in order to perform Salah (Prayer). I now ask whether I should change the wet underpants (Part No. 4; Page No. 243) at the time of each Salah, bearing in mind the great difficulty involved in this matter when I am at work or in a lecture that lasts from Maghrib (Sunset) to `Isha (Night) Prayers, given that I perform Wudu' (ablution) for every Salah, but changing my clothes becomes very difficult for me. Should I wear a diaper until the end of the day as long as there is not much wetness?Is it permissible for me to combine two Salahs with one Wudu' when traveling or at times of rainfall?Is it permissible for me to wipe over my socks?Is it permissible for me to occasionally perform Wudu' a few minutes before the time of Salah is due so that I become able to perform congregational Salah, as in the case of being in Makkah in order to avoid people crowding in the bathroom?What is the ruling concerning the Salahs I offered in the past whose number I do not know and for which I performed Wudu' before they were due?

A: Firstly, you should wear a diaper to prevent any Najasah (ritual impurity) from staining your underpants. You have to change this diaper if it is contaminated by any Najasah. As for your underpants, you do not have to change them as long as they are not contaminated by any Najasah.Secondly, there is nothing wrong with you attending religious lectures and lessons as long as you are certain that no Najasah will be caused to the Masjid. (Part No. 4; Page No. 244) Thirdly, a person suffering from urinary incontinence should perform Wudu' for each Salah after the beginning of its due time. If he combines two Salahs while in travel or due to rainfall, one Wudu' performed for both will be sufficient for him, because offering both at the time of the earlier or the later of the two is considered one time of Salah. Furthermore, it is permissible for you to wipe over the Khuffs (leather socks) if you wear them while in a state of Taharah. As for performing Wudu' before the time of Salah is due, we hope that Allah may forgive you. You should also continue offering Qiyam-ul-Layl (optional Prayer at night), reciting the Qur'an, and attending the circles of learning. Do not let Satan deceive you; rather, you should be patient in the face of adversity and you will be greatly rewarded. We ask Allah to cure you and make you steadfast in the truth. May Allah guide us all to what pleases Him.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
