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.

Spiritual experiences

Q: I need a sure and definite answer to this question. Actually, when I close my eyes and concentrate, I can see things and visit places and communicate with the jinns. I also get feeling when something bad will happen. Some months ago, my sister was very sick and I got the feeling that it was a sorcery. My mom knew a person which also know these things, so she called him and as I concentrate, I could describe the person who had done the sorcery well and the person which my mom called communicated with him through me as intermediate asking the shaitaan or jinn where he comes from etc. Sometimes, they take my body and I talk things beyond my comprehension. Finally, the person, through recitation of Quran, the jinn was forced to break the condition of the sorcery like coconut, blood and lemons etc. and some were burnt and some converted to Islam. I could see them burning and becoming ashes and some converted to Islam and go to mecca. My sister was then recovered fully from the disease. I want to know if this is allowed to use the inner eye or is it and how is it shirk? The power is in me but I don't know if I can make use of them. I have read about roqya to recover from black magic but the black magic is very complicated and powerful. Sometimes, the jinns or shaitaan have protection and they does not get affected when reciting quran. If it is not allowed to use the concentration or inner eyes to break the black magic's work, how can we combat it fully?

Hadith related questions

Q:

1. I'm a bit wary about hadith. People only talk about Bukhari and Muslim. Has Abu Dawood, Tabrani, and Tirmizi also have authenticity or are they weak or in between?

2. Lots of kitaabs mention Sura Yaseen as the heart of the Qur'an, that for the regular reciter, all his needs for the day are fulfilled, and for the regular reciter, it removes the afflictions of this world and the next and removes dread of the next life. Are these hadith sources about Sura Yaseen authentic?

3. It is said that regular recitation of Suras Mulk and Sajdah will protect one from the punishment of the grave and one will receive the reward of staying awake during Laylatul Qadr. Is this authentic?

4. It is said that the person who stays awake after Fajr and performs Salaatul Ishraaq and if he dies on that day he will directly enter Jannah. (Tibrani) Is this authentic?

Sorry for posing so many questions, the local ulama seems to always be so busy. I would really appreciate it if you could answer these questions for me because rewards of ibaadah really motivates me and helps me to stay consistent.

Wife committing zina

Q: My wife had sex with one of her contacts. She slept with him on the first time they decided to meet at his place and she only chatted with him for a month. They slept twice together on different days. She always promised me she will never have sex with another man even after the time she had sex with him for the first time. She use to tell me it's her cousin and convinced me with tears in her eyes that how can I suspect her with her cousin, so I believed her. When I thought I don't like this chats that she and her so called cousin had, I deleted his contact then she hit me and threw tantrims telling me it's just her cousin. But I found out it wasn't and they had sex twice. So my question is, it wise to let her go work after all the lies and deceit and betrayal? Must I trust her promises and word this time? I mean if she found it easy to sleep with a stranger what about someone at work or someone she travels with. Please advise me.

Using gold and silver as a treatment

Q: I am having treatment from arvyeda doctor. He uses Indian method and Chinese method of healing and he also uses reiki . He uses needles that are used in acupuncture. Needles made of gold and silver. That doctor told me to drink from pure silver cup and eat from our silver plate. My health was very bad. I was very bad and I was absent minded all the time. Now it's better much better. Now my health is getting better. The doctor told me not to leave this treatment. He also recommend me to wear a gold ring. As this will also be useful for my health. He told me that gold has proven health benefits by scientists and some researchers. He also told me to wear silver chain men style. Maybe later he will tell me to drink in gold. Is it allowed in Islam to drink in silver and gold and men to wear gold for treatment purposes?
