Question: We offer prayers in Jamat at our office without giving Adan because we all hear Adan from near surroundings.
Answer: Assalamu alaikum wa rahmatullahi wa barakatuh,
I hope you are in the best of health and spirits, insha’Allah.
According to the Hanafi school, if the call to prayer is given in one’s vicinity, the sunna would be fulfilled and it would not be disliked to leave it. [Haskafi, al-Durr al-Mukhtar]
It would however remain recommended to give the call to prayer (adhan) when reasonably possible.
And Allah knows best.
