you must have read this ,but worth re-reading

*Azaan a miracle? Yes!*
*Amazing as 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 on the eastern side of the earth. The major cities of Indonesia are Java, Sumatra, Borneo and Saibil. As soon as dawn breaks on the eastern side of Saibil, at approximately
5:30 am local time, Fajar Azaan begins.
Thousands of Muazzins in Indonesia begin reciting the Azaan. The process advances towards West Indonesia . One and a half hours after the Azaan has been completed in Saibil, it echoes in Jakarta . 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 beginning in Jakarta, it reaches Dacca, the capital city of Bangladesh . After 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 proclamation. Srinagar and Sialkot (a north city in Pakistan ) have thesame timing for Azaan. The time difference between Sialkot , Quetta , and Karachi is forty minutes, and within this time, Fajar Aazaan is heard throughout Pakistan . Before it ends there, 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 (Holycities 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. The time difference between eastern and western Turkey is one and a half hours, and during this Alexandria and Tripoli (capital of Libya ) are located at one hour’s difference. The process of calling Azaan thus continues throughout the whole of Africa . Therefore, the proclamation of the Tawheed" and "Risaalat" that had begun in Indonesia reaches the Eastern Shore of the Atlantic Ocean after nine and half hours.
Prior to the Aazaan reaching the shores of the Atlantic, the process of "Zohar Azaan" has already started in east Indonesia , and before it reaches Dacca , Asr Azaan" has started. This has hardly reached Jakarta one and half hours later, the time of "Maghrib" becomes due, and no sooner has "Maghrib" time reached Sumatra , the time for calling"Isha Aazaan" has commenced in Saibil! When the Muazzins of Indonesia are calling out "Fajar Azaan", the African Muazzins are calling the Azaan for Isha.
If we were to ponder over this phenomenon thoughtfully, we would conclude the amazing fact that there is not even a single moment when hundreds of thousands of Muazzins around the world are not reciting the Azaan on the surface of this earth. Subhaan Allah !!!
Even as you read this material right now, you can be sure there is Azaan
somewhere !!!
