Qiraat

Q: If I am reading 4 rakaats Sunnah salaah and I read surah Naas in the first rakaat, what must be read in the remaining 3 rakaat?

Q: A person was offering fajr and recited Surah Al A'laa in it. However, the person missed 4 ayat in the middle of the surah (from ayah 12 to ayah 16) and also did not do sajdah sahw. Should the prayer be repeated?

Q: Is the following makrooh:

1. To read a shorter Surah in the first rakaat and a longer Surah in the second rakaat?

2. To read a Surah in the 1st rakaat and then skip a Surah and read the next Surah in the second rakaat?

3. To recite Surahs in the wrong order in salaah?

Q: I have been told that we cannot pre determine what surahs we going to read before commencing salaah. This came up when I told someone that I have first rakaat surahs, second rakaat surahs & so on, so I do not make a mistake or forget which rakaat I am currently reading.

Q: In the third or fourth rakaat of a four rakaat fardh salaah, a person mistakenly recited a surah after Surah Faatihah. If sajda-e-sahw is not made, is the salaah valid or does the salaah need to be repeated?

Q: The first rakah of fajr should be long. Is it for the two rakah sunnah or the fard only?

Q: I was a masbooq for esha salaah and in the surah after surah fatiha I think I missed out a few words in surah nasr in the last aayat due to some disturbance. I think the words were 'was tagh fir'. In this situation do you need to make sajda e sahw and do I need to repeat my salaah?

Q: I would like to know if I can pray these 3 surahs in my tahajud salah; surah waqia, surah mulk and surah sajda because I pray out of salah so I can add them to my tahajud salah.

Q: If a person read Surah Naas in the first rakaat, what should he read in the second rakaat? Is this for nafl and for fard salaat?

Q: If I am offering prayers alone then can I read qirat (reciting Holy Quran) in a loud voice? If there is no person except me.
