If the muezzins differ, who should be followed with regard to breaking the fast?
Question

                If the adhaan differs from one mosque to another, and two of them are close together and in the same area, which one of them should be followed with regard to breaking the fast?.
Praise be to Allah.What matters with regard to 
    breaking the fast is the setting of the sun, as the Prophet  (peace and 
    blessings of Allaah be upon him) said: “When the night comes and the day 
    departs, and the sun sets, then it is time for the fasting person to break 
    his fast.” Narrated by al-Bukhaari (1954) and Muslim (1100). 
What is meant by setting is 
    when the disk of the sun disappears. No attention is to be paid to the red 
    glow that remains on the horizon. So when the disk of the sun disappears, 
    then it becomes permissible to break the fast. 
Most of the muezzins 
    nowadays rely on timetables, and there is nothing wrong with that, but some 
    of them fall short in making sure that their clocks are accurate, as they 
    should. 
If the muezzins differ, 
    then you should either see which of them is more precise in timekeeping and 
    gives the adhaan at the beginning of the time, not too early or too late, 
    and rely on his adhaan and no other; 
Or you can rely on 
    timetables yourselves, after making sure that your clocks are accurate, even 
    if the muezzin has not yet given the adhaan.
And Allaah knows best.
