Azaan(+vdo) is not a part of the Salat & Salat

The  Call to Prayer (Azaan)
Azaan is not a part of the Contact Prayers, nor is it required.
.
But it has become a tradition in the Muslim communities to summon the people to prayer through a loud announcement.
.
The original Azaan used to conform with the Quran's teachings, and became corrupted with time.
.

Originally, the call to prayer consisted of:-
.
Allahu Akbar (God is Great), 4 times.
Laa Elaaha Ellah Allah (There is no other god beside God), once.
.

Many years later, some people added Muhammad's name to the Azaan.
.
This violates God's commandments in 2:136, 2:285, 3:84, 4:150 and 72:18. Later, other groups of Muslims added the names of Ali and his family.
.
Today, the Azaan is severely corrupted throughout the Muslim world, and constitutes idol worship, not Submission to God ALONE.
.

The Correct Azaan
If you pray by yourself, an Azaan is not needed. The Azaan is usually observed when a group of people are ready to observe the prayer. One person stands up and utters the Azaan words, or chants them as follows:-
.

Allahu Akbar, Allahu Akbar (God is Great, God is Great).
Allahu Akbar, Allahu Akbar.
La Elaaha Ella Allah (There is no other god beside God).
.
