1. It is Sunnat-e-Mu’akkidah to invite the Muslims to each Fard Salaah through calling out the Azaan.
2. The “Mu’azzin” is the person who calls out the Azaan.
3. It is the Mu’azzin’s duty to remember the correct times of Salaah and the manner of reciting the Azaan.
4 The Mu’azzin:
4.1 must be in a state of Wudu,
4.2 must stand in a specific place made for calling out the Azaan,
4.3 must face the Qiblah,
4.4 must place his Shahaadah fingers in his ears, and
4.5 call out the Azaan in a loud voice.
5. The Mu’azzin must avoid calling out the Azaan in a singing style.
6. The Arabic words of the Azaan must be recited with a “pulling” tone only at those places where it is permissable to “pull.” Therefore, it is necessary for the Mu’azzin to know Tajweed.
7. The Azaan must be called out in a clear and simple manner.
8. One should repeat the words of the Azaan after the Mu’azzin. However, after you hear: “Hayya alas Salaah” and
“Hayya alal falaah,” you should say : “There is no Help or Strength except that which comes from Allah.”
9. If one hears the Azaan being recited and is not in the Masjid, one must immediately go to the Masjid for Salaah.
10. After Azaan, it is a great Thawaab to lift both hands and read the Du’a After Azaan.
11. It is also Mustahab to kiss both fingernails of the thumbs and rub them over the eyes when you hear the Mu’azzin read:
“I bear Witness that Muhammad is the Messenger of Allah.”
11.1 The first time that you hear “Muhammaddar Rasulullah” (sallal laahu alaihi wasallam), you should say: “O Rasulullah! The coolness in my eyes is through you.”
11.2 The second time that you hear the same, you should say: “O Allah! Make me enjoy vision and sight.”
This was a practise of Sayyiduna Rasoolullah’s (sallal laahu alaihi wasallam) beloved Sahaba, Sayyiduna Abu Bakr (radi Allahu anhu). We must also make this our practise as there is great Thawaab in this.
12 . When the Mu’azzin says: “Hayya alas Salaah” he should turn towards the right each time.
13 .When the Mu’azzin says: “Hayya alal Falah” he should turn towards the left each time.
Remember, do not turn the shoulders and the entire body, but only the face.
