Method of Salaah

Q: I was sad for a moment during salah and I think my throat strained and my recitation jerked slightly. Is my salah fine?

Q:

1. When we read durood in namaz or in general we say Muhammad, so do we have to say sallallahu alaihi wasallam 4 times?

2. What are the rewards of just saying sallallahu alaihi wasallam, like how durood has its rewards? 

Q: An Imaam performed Fajr Salaah, he recited Surah غاشية. In this Surah he read وجوه يومئذ غاشية instead of خاشعة. Will the Salaah have to be repeated?

The Imaam occasionally gets confused between laam and raa, should he be making Imamat?

Q: Can I say aamen in sujood after making dua and after Durood in namaz? 

Q:

1. When a man is praying maghrib alone, is it best for him to recite loudly or silently? 

2. If he chooses to recite loudly, should he also say the takbeers, samiAllahu liman hamidah etc loudly as well just as an imam would have done?

Q: A few weeks ago an email was sent under the heading azkaar after salaah. It mentions putting the hands on the head and reading for the removal of worry and grief. Can Mufti saheb please send me that azkaar. 

Q: What is the ruling regarding jahari and sirri salah behind an Imam? Does the muqtadi (follower) recite anything in both salah?

Example: The last one and two rakats of Maghrib and Esha farz respectively. Should he recite surah fatiha or should he remain silent?

Q: My question is regarding the method of jamaat namaz:

1. If someone is offering namaaz with jamaat, should he be required to recite “Surah-fatiha” and a surah after that if the imam is reciting it?

2. Now in the case of Zuhr and Asr prayers (when imam is not reciting loudly Surah fatiha and Surah) do the people have to recite it or should they simply stand quiet?

3. In the last 2 rakats of a farz namaaz, I know that surahs are not recited after surah fatiha, I just want to confirm this from you?

4. If I join the jamaat in the rukooh of the first rakaat, I don’t need to repeat the 1st rakaat (this is what I understand); now when will I recite the thana “subhanakaALLAH...” ?

Q: Is saying 33 SubhanAllah, 33 Alhamdulillah and 34 times Allahu Akbar after each prayer rewarding? 

Q: While reciting Quraan in prayer, if one recites first two verses of a surah but forgets to reicte the third verse and goes on to the fourth verse, meaning he has recited total of three verses but had omitted one verse in between by mistske, would the prayer be valid?
