Salaah

Q: When we are in the masjid and iqaamah has already started, sometimes a person in the first row moves back to make space if another learned Maulana arrives, even though there are already a few learned Ulama present in the first row. 

Should we move from our place to give space to a Maulana at that time, or should we remain focused and avoid movement so we can prepare ourselves to stand before Allah? What is the correct adab according to the sunnah?

Q: Is it permissible to read salaah on the mataaf in jamaat, as this is technically reading in front of the imam? Previously the imaams would perform on the mataaf/hateem, but not anymore.

Q: I am praying taraweeh in a place where five times prayers are offered throughout the year but not the Jumuah prayer. It is a small place with fixed Imam. 

Can we pray Esha here or should I pray Esha in a bigger nearby masjid and then go there for taraweeh?

Q: In my masjid, the qiblah is off by a bit. In between 35 - 43°. (Closer to 40° in most apps) 

They are getting new carpets fitted insha Allah. However, the committee are disputing on whether to face it to the qibla or keep it as it is. They will lose a few musalla spaces if they angle the carpets and it will make the carpets not match the building which they don't want. 

I've said, although the salaahs may be valid, it would be best to angle it and go closer to the qiblah, preferably within 20°. Could you give a final answer into the matter?

Q: If one thought he was musaafir and read 2 rakaats for his namaaz, but after that he found out that he was not a musaafir. What must one do? Does he repeat his namaaz?

Q: If the Imaam in the Haram reads a sajdah aayat in maghrib, and the musallees not knowing the imaam went into sajdah, instead go into ruku, and thereafter they join the imaam again in the remainder qiraat, is the salaah of the musallees valid?
