Qiraat in Salaah

Reciting in sequence in Salaah

Q:

1. When reading surahs in our Salaah is there a specific sequence to choose a surah to read? e.g. Do we have to start from Wadduha then followed by the next surah?

2. Is it ok to read a short Surah followed by a longer one? e.g. Wal Asr and then Izaajaa'a. Please explain what is the correct way?

Reciting a Surah in the third and fourth rakaat after Surah faatiha in the four rakaats sunnat of zuhr

Q: I just wanna ask about the sunnat-e-muakadah before fardh of zuhr. I should perform it with salaam at the end and now my question is on the third rakaat am I only going to recite fatiha and also in the forth rakaat just like praying fardh or I should recite another surah in the third rakaat and another surah in the last rakaat after faatiha?
