Etiquettes and respect for the Quraan

Playing a recording of the Quraan Shareef in the house

Q: For a very long time we used to hear noises in the house at night. We would hear people walking up and down the stairs, down the corridor, chairs moving and the bathroom taps open at night. Even some that would visit could hear the sounds. We would get sick very often but every time we went to doctors and did various tests it would all be clear. Nobody could tell us what was wrong with us.

From the beginning of the year we started playing Quran Sharief in the house in the background 24/7. Ever since, we haven't had any issues Alhamdulillah. We stopped hearing the sounds and our health has been better. Alhamdulillah Is this disrespect to the Quran Sharief?

Reciting the Quraan Shareef on a phone while sitting behind a person

Q: If a person is sitting in the masjid in the 3rd or 4th saff with people sitting in front of him and he is sitting at the back of them, can he read Quraan on the mobile. Will it be dishonouring the Quraan as he is sitting at the back of person and reading Quraan on the mobile. It means the Quraan is at the back of a person.

Can one read Quraan in the Haram of Makkah when people are doing tawaaf, or sitting in front of a person, or will it be not correct?

Ordering a Quraan online

Q: Recently I ordered a Quraan Sharif with English translation from Amazon. They delivered my order to my door.

My question is that now I'm feeling very conscious of how and who might have handled the Quraan and if it's ok that they put the package in front of the door on the ground? I feel very upset and regret ordering it online but I had no other option at the moment. Would I get sin for it?
