امت کی مضبوطی

When the Muslims arrived at Medina, they used to assemble for the prayer, and used to guess the time
for it. During those days, the practice of Adhan for the prayers had not been introduced yet. Once they
discussed this problem regarding the call for prayer. Some people suggested the use of a bell like the
Christians, others proposed a trumpet like the horn used by the Jews, but `Umar was the first to
suggest that a man should call (the people) for the prayer; so Allah's Messenger (ﷺ) ordered Bilal to get up
and pronounce the Adhan for prayers.
