During the blessed times of the exalted Prophet and Sahaba Kiraam, people were called to the Masjid only when necessary for serious official or social reasons. "AS-SALAAT-IL-JAAMI'AH, AS-SALAAT-IL-JAAMI'AH" (Salaat Congregation, Salaat Congregation!)
ROLE OF THE MASJID:
One thing that instantly facilitated efficient governance in the Islamic State was a wide network of mosques serving as government centers. From the very first year of Hijrah, Muslims had been building mosques in their locales. The Federal, provincial and township governments oversaw that mosques were built in proper locations in every neighborhood. One call from the Muazzin (caller of Azaan), "As-Salaatil Jami'ah" used to be sufficient to assemble the available men and women to the Masjid. There was no clergy or "Imams" to run and manage these Masjids or conduct congregations. The government official of each area was the leader of the area mosque. The Masjid was not a temple of worship. It was the School, the Assembly, the Municipality, the Parliament and the Government House. The respective leader would discuss real issues about the community, entertain questions, present bills, announce decisions of the Shura (Counsel) and the Assembly would legislate. People came up with their ideas for betterment of the society and devised plans for social welfare. Every citizen remained informed of the condition of the needy, the orphans, the sick and the widows. People brought up news of any socioeconomic problems facing any families and they were immediately addressed. What a cohesive System! Masjid was also the place where the leaders and officials were elected, ambassadors received, and defense matters decided. What a convenient and ready-made infrastructure for the government and public! Later on, a Hadith was invented that it was Haraam to discuss "wordly matters" in the mosque. Alas! With this single stroke of pen, by the third century Hijrah, the Masjid had been reduced to what we see today, a temple of worship with empty rituals!
Microphone/Loud-speakers for Azaan: What a grim violation of human rights! The history here is funny. I will get it typed tomorrow :-)
