Preparing in advance for Salaah due to urine problems

Q: Islam is a religion of ease not of hardship, it is very well mentioned in the Qur'an and hadith about this easiness. I am suffering from urine incontinence. I have realised that I am not a mazoor, but for praying one namaaz I have to make wudhu 3 to 4 time and every time I have to wash my private part, whether I pray on time or later I have to face this hardship. It is really very difficult. So why there is hardship when there is so much easiness in Islam? I am missing my salaah because I can't take this hardship. I am really upset with myself because I can't worship my Allah who has given me so much. Please help find a easy way for me.

Performing nafil Salaah in jamaat

Q: During Ramdhaan in the Haramain both at Makkah and Madinah they conduct Tahajjud namaaz in Jamaath during the last 10 days from 1 am to 2.30 am. Following this now a days the same method is being followed in mosques in our country (India) as well and also women participate in this congregation but of course in a enclosure segregated for women. Also now a days women attend Jummah namaaz in mosques on a regular basis. Please give your expert option on these two issues.

Joining Salaahs

Q: I traveled from Cape Town to KZN for work for approximately 10 days. My work requires much travel to far flung places like Durban, Harrismith, Van Reenen and Vryheid. Based on the locations of the work areas, can I combine my salaah for my entire stay in KZN or should I make salaah separately after three days?
