Doubting if one is paak

Q: If I am not sure if I am sexually napaak and I have my periods and if I shower not for paaki but just a shower, will everything I touch become napaak and since my hair will be wet after showering if any drops fall will they make things in the house napaak and since I have school and wear my coat and bag will they become napaak also? Since I can't wash that what should I do? And has my bed and every other place before showering become napaak now?

Reading inappropriate literature

Q: I was reading a text that was inappropriate not intentionally and it wasn't descriptive at all it just had an inappropriate word (sexual). Since I read it am I napaak now? and am I that type of napaak even if I have my periods? If I have sat on many places are those napaak now as well? Please help. This has been bothering me since the morning when I had read it.

OCD problem

Q: This morning I thought fajar happened around 6:35 so when I woke up around 6 I thought there was still time to pray. I went and made wudu and I am kind of sure that the sky was dark but there was like a very faint light when I started. I didn't think it was that late so I started praying. I struggle with OCD so it takes me a while to pray even four rakaat and when I was done the sky was still dark but it was a lighter blue colour. Did I pray at a forbidden time? Did my namaaz not count? I am so doubtful and my OCD makes everything so hard can you please tell me what I should do? If I have to repent or make it up do I read the prayer of repentance after making wudu?

Haraam relationship

Q: I am going out with a girl and I knew her from the internet and we didn't meet yet. I tried to stop but she is a Muslim but her parents aren't that good in Islam. But she wants to get better in Islam so I didn't stop. We decided not to meet until we tell our parents, so I don't know what to do. Tell me what to do please?

Azaan

Q: Please advise regarding the Azaan:

(1) Should Masnoon Dua's be recited during the Azaan? For example, the Masnoon Dua's for entering the Masjid, when boarding a vehicle, when leaving the home and so forth.

(2) If a person is standing during the Azaan, should he remain standing until the Azaan has been completed before he sits down/performs Salaah?

(3) A person enters the Masjid just before the Muazzin is about to commence the Azaan. Is it correct for him to commence Tahiyatul Masjid or Sunnah Salaah at this point i.e. a few seconds before the Azaan? In this manner, almost his entire Salaah will be performed during the Azaan.

(4) It is often observed that those who arrive early to the Masjid (much before the Azaan and within the Salaah time) only perform their Sunnah Salaah after the Azaan has been given. It gives the impression that they were waiting for the Azaan in order to perform their Salaah. Is this correct?

(5) Should one greet a person with Salaam and shake his hands during the Azaan?

(6) Should one respond to the Salaam of a person during the Azaan?

(7) Can one verbally inform others to keep quiet during the Azaan whilst the Azaan is going?

(8) Should one respond to the Azaan heard over a recording or live streaming audio?

(9) Should one avoid 'answering the call of nature' during the Azaan?

Joining two Salaahs

Q: I have heard one is able to join prayer like zuhr and asr when need be. I am a student and I can never get any work done at home so I go to the library. Only the time between the two namazes are like three hours. Is it ok for me to join the two in this case because that gives me so much more time to sit there and get my work done?
