The times of the prayers are close together in the North – is it permissible to put them together?
Question

                I would like to know the options muslims would take with regards to the J'amaah Prayers in the following situation :- 
      Maghrib time 10:00p.m
      Isha time 11:15p.m
      Fajer 1:50a.m
      To explain more my question, I would like to know the fatwa into options muslims would
      take when the times of the Maghrib,Isha and Fajer are extreemley close to each other. So
      therefore, is it allowed to pray Maghrib & Isha together or what ? And if yes what is
      the Proof from the Qura'an & Sunnah , and if no , still what is the proof ?
Praise be to Allah.The time of Maghrib prayer lasts from sunset until the
    red afterglow disappears; the time of ‘Ishaa’ prayer lasts from after the red
    afterglow has disappeared until midnight; the time of Fajr prayer lasts from the second
    dawn until sunrise. The evidence (daleel) for this is the hadeeth of ‘Abd-Allaah ibn
    ‘Amr ibn al-‘Aas in Saheeh Muslim in which this is mentioned. So long as
    the times of the prayers are distinct from one another, each prayer must be performed in
    its own time, even if the times are close together. Being patient in doing this is a kind
    of jihaad, and Allaah does not cause the reward of the one who does good to be lost.
