The Lofty Status of the Muazzin

عن عمرَ رضي الله عنه قال
لو كنتُ مؤذِّنًا لكَمُلَ أمري، وما بَأَلَيتُ أن لا أَنتصِبَ لقيامِ ليلٍ ولا لصيامِ نَهارٍ.
سَمِعْتُ رسُولَ اللهِ صلى الله عليه وسلم يقولُ: اللَّهُمَّ اغفِرْ للمؤذِّنينَ ثلاثًا.
قُلتُ: يا رسولَ اللهِ، تَرَكْتَنا ونحنُ نَجْتَلِدُ على الأذانِ بالسيوفِ
فقالَ: لا يا عمرُ، إنَّهُ سيَأتي زمانٌ يَترُكونَ الأذانَ على ضُعَفائِهِم.
تِلكَ لُحوم حَرمَها اللهُ على النارِ: لُحوم المؤذِّنينَ

It is reported regarding Hazrat Umar (Radiyallahu anhu) that he had said, “Had I been able to call out the azaan (together with managing the affairs of khilaafah), certainly my happiness would have been completed. (The reward of calling out the azaan is so great that if I had the honour of being a muazzin and) if I had not performed any nafl salaah during the night (tahajjud) nor kept any nafl fast during the day, it would have not grieved me. I heard Rasulullah (Sallallahu alayhi wasallam) making special dua for the muazzins of this Ummah saying, ‘O Allah, forgive the sins of the muazzins!’
Rasulullah (Sallallahu alayhi wasallam) made this dua three times. 

In surprise, I said, ‘O Rasulullah (Sallallahu alayhi wasallam)! (You have elevated the position of the muazzin to such an extent that) you have now left us in the condition that we will be prepared to fight amongst ourselves with our swords in order to call out the azaan.’ Hazrat Nabi (Sallallahu alayhi wasallam)said, ‘No, O Umar! A time will come where the desire of calling out the azaan will no longer be in the hearts of people, to such an extent that people will rely on the weak among them to call out the azaan. Those people (the muazzins) are such that Allah Ta'ala has made the fire of Jahannum haraam on their flesh, the flesh of the muazzins.’”
