Ma'zoor changing his clothes before each Salaah

Q: I am suffering from incontinence of urine. I know I am a mazoor and have to make wudhu, but I am finding it very difficult to wash the private part and to wash or change clothes for every prayer. It is getting very hard for me to pray. Please find an easy way for me to pray namaz and quran. I am very much afraid of not praying. I don't want to spoil my aakhirat. I want to be close to Allah Ta'ala. Please guide me according to Islam.

Cleaning the floor of impurities

Q: You have always helped me in my doubtful issues. I am a very doubtful person and often doubt purity. Please let me know if sperm drops on the floor and I can't figure out exactly where they fell and whatever I could see I cleaned them with a dry and wet tissue. Now I am doubting that what if I missed more spots or what if while finding the spots I stepped on one and now I feel the whole house will be impure wherever I will wear the slipper. Also if I have missed a spot and if I mop the floor will whole house be impure to pray.

Performing a Secret nikaah and thereafter re-performing the nikaah

Q: My daughter received a wedding proposal. We have accepted, but the problem is the boy can only marry her when he has completed his studies [1 year's time]. The kids want to see one another. Can we have a contractual nikkah now, no hankie pankie, but just spend time in parents presence, then when he can earn a living have another nikkah and they can now live as man and wife Insha Allah. What can you advise mufti. We don't want the kids to do zinnah/fitna and we understand that the boy wants to finish his studies, both sides of the parents can't afford to maintain the new couple now. Please advise.
