It is disliked to sing the Adhan in the sense of elongating the words excessively without changing the meaning. If the meaning is changed, then it becomes prohibited and the Adhan is not correct in this case.

1- The correct view is that adhan is fard kifayah (a communal obligation); if someone who is competent does it, the rest are absolved of sin. 2- If a person starts to pray without the adhan or iqamah, whether out of forgetfulness or ignorance, or for some other reason, the prayer is still valid. 3- If a muadhdhin gives the adhan in one neighborhood and all the residents can hear it, that is sufficient.

The adhan and iqamah are only for the obligatory prayers. But for Tarawih, Witr and other optional (nafl) prayers, there is no adhan or iqamah.

Two forms of the iqamah have been narrated from Prophet Muhammad (peaceand blessings be upon him); one form has 11 phrases and the other has 17 phrases.

1. There is no du’a to be recited before the adhan. 2. There are no specific words to be recited before the iqamah. 3. Du’a is highly recommended between the adhan and the iqamah. 4. There is no du’a after the iqamah. 5. It is Sunnah to repeat what the muadhdhin is saying. For more, see the detailed answer.

Whoever gives the Adhan for twelve years will be guaranteed Paradise, and for each day sixty Hasanat will be recorded for him by virtue of his Adhan, and thirty Hasanat by virtue of his Iqamah.
