Recitation and Listening to the Quraan

Q: I have a few Surahs recorded on my cell phone and I have kind of developed a habit of listening to it when I go to bed at night. Is it okay and is wudhu compulsory? Please advise.

Q: Is it permissible to listen to the Qur'an while exercising?

Q: Whilst reading Qur'an, if a person knows Arabic and comes across an ayat where there's a command to glorify Allah or seek refuge with Him, and the person makes dua accordingly, do they have to recite ta'awwuz again before they resume the tilawat? Would the rulings be different if they made the dua in a language other than Arabic?

Q: Alhamdulillah and thanks to Allah for all his blessings amongst us. Alhamdulillah who favoured me over many other creations by blessing me with a melodious voice and gave me a wealthy life. My question is that once in my class at school our teacher told us that those who read the Qur'an with nice voices with the intention to please people and impress them with his voice is one of the people of hell and that actually shocked me and kept a "waswasa" in me whenever I'm reading Qur'an in front of the school or my class mates so I don't participate in such activities much anymore. What should I do because I totally doubt that my intention is pure.

Q: Can you recite the Qur'an from memory or listen to the Qur'an while you are doing some work or playing? Can you listen to the Qur'an while you are driving or cleaning?

Q: What is the ruling for reciting those verses of the Qur'an which have no harkat at the very first hurf? E.g verse no.5 of surah al ma'oon. What is the ruling to start reciting this ayat with 'zabar' on alif if we stop at the previous ayat? Likewise we start some ayaats with 'zair' harkat on the first hurf if we don't find any harkat at the first hurf. e.g verse no. 28 of surah al'fajr'.

Q: Can I recite the verse of the Quran while walking down the streets? Note that I have not done ablution.

Q: My question is that when I'm just going through the streets can I recite the verses of the Quran if I do not have wudhu?

Q: I was reading the Quran at zawaal time about half an hour before Zohar time. Someone told me to stop praying because we are not allowed to pray at that time, is this correct? I thought just sajda was forbidden. Are we allowed to read Quran before sunrise?

Q: A friend of mine is unsure whether you can recite the Qur'an during haidh as the teacher who takes her for hifz says it is permissible. My friend wants proofs/authenticity regarding it not being permissible.
