An incredible medium for the proclamation of Tawheed of Almighty Allah and Risaalat of Prophet Muhammad Sallallahu Alayhi Wasallam, the sound of which constantly echoes around the globe.Amazing though it sounds, but fortunately for the Muslims of the world, it is an established fact.

Have a look at a map of the world and you will find Indonesia(an Islamic country) right on the eastern side of the earth's central land mass. Indonesia consists of numerous small islands, the principle ones amongst them being Java, Sumatra, Borneo and Saibil, all of which are well known. It is the largest country in the world,with 180 million inhabitants. The number of non-Muslims here is negligible.

As soon as dawn breaks on the easternside of Saibil,at approximately 5:30 am
local time, Fajar Azaan begins. Thousands of Muazzins in eastern Indonesia commence proclaiming the Tawheed(oneness) of the Almighty, Omnipotent and Omniscient Allah and Risaalat(Universal Apostleship)of the Prophet Muhammad Sallallahu Alayhi Wasallam. The process then continues and advances towards the Western Islands of Indonesia. The time difference between the eastern and western islands of Indonesia is one and a half hours. Hence, one and a half hours after the Azaan has been completed in Saibil, it echoes in Jakarta on Java island. Sumatra then follows suit and before this auspicious process of calling Azaan ends in Indonesia, it has already begun in Malaysia. Burma is next in line, and within an hour of its commencement in Jakarta, it reaches Dacca,the capital city of Bangladesh. No sooner the calling of Azaan ends in Bangladesh, it has already Prevailed in western India, from Calcutta to Srinagar. It then advances towards Bombay and the
environment of entire India resounds with this august proclamation. Srinagar and Sialkot (a city in north Pakistan) have the same timing for Azaan. The time difference between Sialkot, Kota, Karachi and Gowadar city in Baluchistan, a province of Pakistan) is forty minutes, and within this time, Fajar Azaan is heard throughout Pakistan. Before it ends there, however, it has already begun in Afghanistan and Muscat. The time difference between Muscat and Baghdad is one hour. Azaan resounds during this one hour In the environments of hijaaz-e-Muqaddas (Holy cities of Makkah and Madinah), Yemen, United Arab Emirates, Kuwait and Iraq.The time difference between Baghdad and Alexandria in Egypt is again one hour. Azaan continues to resound in Syria, Egypt, Somalia and Sudan during this hour. Alexandria and Istanbul are situated on the same
geographical longitude. The time difference between eastern and western Turkey is one and a half hours, and during this time it is echoed with the call to prayer. Alexandria and Tripoli (capital of Libya) are located at a hour difference from one another. The process of calling Azaan thus continues throughout the whole of Africa. Therefore, the proclamation of the Oneness of Allahand the Prophethood of Muhammad Sallallahu Alayhi Wasallam that had begun in the eastern islands of Indonesia reaches the Eastern Shore of the Atlantic ocean after nine and a half hours. Prior to the Azaan reaching the shores of the Atlantic, the process of Zohar Azaan has already commenced in eastern Indonesia, and before it reaches Dacca, Asar Azaan has started. This has hardly reached Jakarta one and half hours later, then the time of Maghrib becomes due, and no sooner has Maghrib time reached Sumatra, then the time for calling Isha Azaan has commenced in Saibil! When the Muazzins of Indonesia are calling out Fajar Azaan, the Muazzins in
Africa are calling out the Azaan for Isha.

If we were to ponder over this phenomenon seriously and studiously, we would conclude the amazing fact that there is not a single moment when few thousands if not hundreds of thousands of Muazzins around the world are not proclaiming the Oneness of Almighty Allah and the Apostleship of the noble Prophet Sallallahu Alayhi Wasallam on the surface of this earth!  Inshah Allah!

This universal and continuous calling of the Azaan shall not cease untill the Day of the Judgement, we should all make necessary effort & du'a for the same .
