Reciting Ta'wuz and Tasmiyah before reciting an Aayat in kitaab reading

Q: When reading a kitaab, like Fazaa'il-e-A`maal for example, one often comes across a single verse or several short verses of the Qur'an Shareef being quoted. (1) Before reciting such a verse, must one recite Ta'wuz and Tasmiyah? (2) Can one just read the English translation below the verse and not the actual Arabic verse itself?

Rinsing the bucket after washing impure clothes

Q: My parents do not understand about najasat much. They clean the impure and the pure clothes together in the same bucket and later they do not wash the bucket and use it again for washing purposes. I have told them that the bucket becomes impure and has to be washed before used again but they are not listening to me and scolding me. When I talk about this now my exams are getting over and I have to go to my home and they wash the clothes the same way as they used to. So if I go and pray with the same clothes after knowing that they are impure will it be kufr and what should I do? Advice me.

Impurity on the floor

Q: When I was in my home many years ago semen got onto the floor (not tiles but smooth floor). I knew nothing about najaasat and all so I just wiped it off with dirty cloth and there was no trace of najasat over there then and later the floor was cleaned with wet cloth and the same cloth is used for cleaning the whole house. Does this make the whole house impure? And if so then the water on the floor which gets absorbed or dried make the floor pure again? If not what should I do now?

Hair dye

Q: I want to ask that if I dye my hair using ordinary dying agents available in the market, would it be an obstacle for my wudhu? Moreover, is it permissible to use dye in black colour?

Talaaq issued over the phone

Q: My husband and I live apart since 2013. He used to come and see me often. He gave me one divorce in 2012 but then we went back together. He gave me another divorce in November 2014 but this time over the phone. When he gave it to me we still stayed in contact due to some paper work issues but he didn't ask me to come back to him neither he came to see me or take me back. I want to know if I am divorced as its been almost 6 months now.
