According to beliefnet;

“A hadith recounts that the Prophet’s companions one day were discussing how to gather everyone for prayer.

Some suggested using a bell as Christians do, and others advised using a ram's horn, following an ancient Jewish practice.

Then Umar, one of the Prophet's companions, suggested having one person call others to prayer. The Prophet agreed, calling his ex-slave, Bilal, to recite the adhan, according to a hadith from the collection of al Bukhari.”

Will praying that community be possible?
