Hadith.914 – Imam al-Ridha 
was reported to have said as mentioned by al-Fadl ibn Shadhan (may Allah (swt) have mercy on him):
"People were commanded to perform the adhan (call to prayer) for many reasons. Among them is that it serves as a reminder for those who forget, an awakening for the heedless, a means of informing those who are unaware of the prayer time due to being preoccupied, and it makes the mu'adhdhin (caller) a proclaimer of worship to the Creator, encouraging others to it, affirming His Oneness, proclaiming faith, and making Islam known to those who might forget. He is called the 'mu'adhdhin' because he announces the call to prayer.
The adhan begins with 'Allahu Akbar' (Allah (swt) is the Greatest) and concludes with 'La ilaha illAllah (swt)' (There is no god but Allah (swt)) because Allah (swt), the Exalted, willed that His Name be mentioned at the beginning and the end. It is repeated in pairs (two-by-two) to ensure that it is heard clearly and emphasized; if one statement is missed, the second will be heard. Furthermore, since the prayer itself is performed in units of two rak'ahs, the adhan was also structured similarly.
The initial four takbirs (saying 'Allahu Akbar') serve to alert the listener since it begins abruptly and there is no preceding word to capture attention.
Following the takbirs are the two testimonies of faith, as the essence of belief starts with the declaration of Allah’s (swt) Oneness and the acknowledgment of the Prophethood of Muhammad ﷺ. These two testimonies are linked because faith is rooted in both recognizing Allah (swt) and His Messenger, and just as other legal matters require two witnesses, so does faith in its complete form.
The call to prayer is then followed by an invitation to salah (prayer), which is the purpose of the adhan, and a call to success and the best of deeds. Finally, it concludes with the mention of Allah’s (swt) Name, just as it began with His Name."
