Azan in quran & Salat in Quran

Where is the call for prayer (Adhan) mentioned ?

وَإِذَا نَادَيْتُمْ إِلَى الصَّلَاةِ اتَّخَذُوهَا هُزُوًا وَلَعِبًا ذَٰلِكَ بِأَنَّهُمْ قَوْمٌ لَّا يَعْقِلُونَ

(5:58) And when you call for prayer, they make it an object of mockery and amusement, this is because they are a people devoid of understanding.

يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا نُودِيَ لِلصَّلَاةِ مِن يَوْمِ الْجُمُعَةِ فَاسْعَوْا

إِلَىٰ ذِكْرِ اللَّهِ وَذَرُوا الْبَيْعَ ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ

(62:9) O you who believe, when the call for prayer is announced on the day of gathering (Friday), hurry to [celebrate] God’s remembrance, and cease all business. It is better for you, if (only) you knew. (62:10) When the salât is finished, then disperse through the land and seek God’s bounty. Remember God frequently, so that you may prosper.
God controls everything and protects the essentials; it is why it is not necessary to provide the detail. For instance, the current call for prayer in the Muslim world is correct if we purify it from the great crime denounced in the Quran:

وَإِذَا ذُكِرَ اللَّهُ وَحْدَهُ اشْمَأَزَّتْ قُلُوبُ الَّذِينَ لَا يُؤْمِنُونَ

بِالْآخِرَةِ وَإِذَا ذُكِرَ الَّذِينَ مِن دُونِهِ إِذَا هُمْ يَسْتَبْشِرُونَ

(39:45) When God ALONE (الله وحده) is mentioned, the heart of those who do not believe in the hereafter are filled with disgust, but when others (other names) are mentioned beside Him, they rejoice.
The ritual prayer has nothing to do with mentioning the name of Muhammad or any other name beside God: It is all about God, and God alone. There is no need to reinvent the wheel, and we simply need to remove that from the current call for prayer:
  4 x الله أكبر
  God is the greatest !
  2 x  أشهد أن لا اله إلا الله
  I bear witness that there is no other god beside God.
  2 x    حي على الصلاة
  Make haste to the ritual prayer.
  2 x    حي على الفلاح
  Make haste towards success.
  2 x    الله أكبر
  God is the greatest !
  1 x    لا إله إلا الله
  There is no other god beside God.
