This Hadith highlights the eminence of Mu'adhdhin and Adhan. Adhan means calling people to the worship of Allah. Mu'adhdhin (the caller) gets reward for the Salat of all those who hear his Adhan. The phrase "will have the longest necks" has been given different interpretations. One of them is that they are those who long for the Mercy of Allah more than anyone else. Another interpretation is that their necks will grow longer on the Day of Requital and so sweat will not reach them, for every one will sweat on that day depending on his deeds: sweat will reach up to one's ankles or knees or waists. In the case of some people, sweat will reach up to their mouths. Another interpretation is that those who call Adhan will have an honourable and great status on the Day of Requital.
