1) One may perform Salaat once the Salaat time of that Salaat sets in. The time between Adhaan and Iqaamat is given to allow Musallees to come to the Masjid. Besides Ramadhaan, when Maghrib sets in the time between Adhaan and Iqamaat is 3 Ayaats.
2) It is Sunnat-e-Muakidah to read the 2 Sunnats before the 2 Fardh of Fajr. One must not leave out the 2 Sunnat of Fajr.
3) Immediately after praying the Sunnats. This does not apply to the administration of timings of the Masjid, Musalla, or Jamaat Khana.
