WE RELATE FROM Abū Hurayrah 
that the Messenger of Allah 
said: “If people knew what was in the call [to prayer] and in the front prayer line and then they had to draw lots for it, they would draw lots.” [1].Al-Bukhārī and Muslim narrated it in their Ṣaḥīḥs.

said: “I heard the Messenger of Allah say: ‘The people who call the adhān will have the longest necks [owing to their uprightness] on the Day of Judgment.’” [3].Muslim narrated it.Abū Sa‘īd al-Khudrī said: “I heard the Messenger of Allah say: ‘Nothing comes within earshot of the voice of the mu’adhdhin—jinn, man, or anything else—that will not bear witness for him on the Day of Judgment.” [4].Narrated by al-Bukhārī.
said: “I heard the Messenger of Allah say: ‘Nothing comes within earshot of the voice of the mu’adhdhin—jinn, man, or anything else—that will not bear witness for him on the Day of Judgment.” [4].Narrated by al-Bukhārī.The hadiths on its merit are numerous.
Our [Shāfi‘ī] colleagues disagree about which is the more meritorious: calling the adhān, or leading the prayer. They have four opinions. The most authoritative is that calling the adhān is better; the second is that leading the ṣalāh is better; the third is that they are equal; the fourth is that if one knows how to fulfil the duties of leading ṣalāh and has the [right] qualities, then leading the ṣalāh is better, but if not, then calling the adhān is the better.
