Qiraat

Q: Does recitation of الله رب العالمين (After Surah Mulk) break ones Salaah?

Q: 

1. During Salah, while I am reciting a surah or something else, must I stop reciting to breathe in or out through my mouth and then continue or can I keep on reciting while I take a breath? 

2. The same question as above for yawning.

Q: The imaan was reading Surah Sajdah. He got stuck repeatedly and paused for more then 3 subhanAllahs. Does salaah need to be repeated because he didn't make sijdah sahw? 

He got stuck like this before. He seems to be ignorant of the masla. 

He also stands with his legs far apart like a ghair muqalid. What should be done in this situation? How should he be corrected?

Q: If a person repeats an aayat of Surah Faatiha to correct a small tajweed mistake, will he have to make sajdah sahw if done forgetfully?

Q: After reciting Surah Ikhlaas in salaah, I mistakenly said sadaqallahul azeem. Is my salaah valid or is there sajdah sahw?

Q: When you want to read a big surah in salaah, but not in full. Is it okay to read from anywhere in the surah and stop anywhere? And can you read one part of a surah in the first rakaat, the part after that in the second rakaat? Or do you have to read different surahs in each rakaat? 

Q: How does one know when to repeat salah if a mispronunciation occurs, e.g. does pronouncing ملحق at the end of dua e qunoot as ملهق, require one to repeat? I.e. Using smalll haa instead of big haa.
