Question: Is it recommended for the mu’adhin to break the fast before the adhan knowing that the laymen say it is necessary that he breaks the fast before the adhan?
Answer: “If he breaks the fast before he makes the adhan, then that is better. For the time has entered:
لا تزالُ أُمِّتِي بخيرِ ما عَجَّلُوا الإفطارَ وأخَّرُوا السُّحورَ
“My Ummah will continue to be good as long as they hasten to break the fast and delay the suhur”
[Reported by Musnad Ahmad (35/241) on the authority of Abu Dharr (may Allah be pleased with him)]
If he does not break his fast until after he makes adhan, then the affair is spacious. There is no harm in that. There is nothing that prohibits it” .
