Salaah

Musaafir performing qasar salaah when staying in a town for less than 15 days

Q: I traveled from Pakistan to Stretford UK where I intended to stay for less than 15 days and during these days will go for a day to Peterborough and come back and then after two days will go for two days to London and come back. Then I will move 15 miles away to Hazel Grove town and will stay there for 20 days. My question is that should I pray qasar salah or otherwise?

Performing Salaah between pillars

Q: In a Masjid, a row is usually left empty after every few rows, as it has several pillars.

1. If it is left empty, is the Salah of those behind it valid?

2. Is Salah valid between the pillars?

3. Once, people prayed in that row to the right of a pillar, but to the left of the pillar the row was empty. Was the Salah of those who prayed to the right of the pillar valid?

Reciting from different surahs in salaah

Q: In one musjid, the Imam Saheb read in the first rakaat of Fajr Salaah from the middle of Surah Tahreem,

يا أيها الذين آمنوا قوا أنفسكم و اهليكم

till the end of the Surah. Then in the second rakaat he read a different surah. Is there any reason for doing so? Would it not be better to start at the beginning of the Surah, read 2 pages, then in the second rakaat finish off the Surah?
