In the Sunnah there are reports that indicate that the muezzin has a status the like of which no one else will have. For example:
1 – It was narrated from ‘Abd al-Rahmaan ibn ‘Abd-Allaah ibn ‘Abd al-Rahmaan ibn Abi Sa’sa’ah al-Ansaari, that his father told him that Abu Sa’eed al-Khudri (may Allaah be pleased with him) said to him: I see that you love sheep and the countryside. When you are with your sheep or in your countryside and the time for prayer comes, then raise your voice with the call to prayer, for no jinn, human or anything else hears the voice of the muezzin as far as it reaches, but he (or it) will testify for him on the Day of Resurrection. Abu Sa’eed said: I heard that from the Messenger of Allaah (peace and blessings of Allaah be upon him). Narrated by al-Bukhaari, 584.
2 – It was narrated that Mu’aawiyah (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: The muezzins will have the longest necks of the people on the Day of Resurrection.” Narrated by Muslim, 387.
Al-Nawawi (may Allaah have mercy on him) said:
It was said that this means that they will be the people who most expect the mercy of Allaah, because the one who is expecting something cranes his neck to see what he is longing for. Or it may refer to the abundance of what they will see of reward. Al-Nadr ibn Shameel said: When the sweat comes up to people’s faces on the Day of Resurrection, they will crane their necks lest that torment and sweat reach them. And it was said that it means that they will be masters and leaders, as the Arabs describe leaders as having long necks. And it was said that it means they will have more followers. Ibn al-A’raabi said: it means the people who have the most good deeds to their credit. Al-Qaadi ‘Iyaad and others said: some of them narrated it as i’naaqan (instead of a’naaqan, meaning necks), meaning that they will be the swiftest to enter Paradise. End quote.
Sharh Muslim, 4/91, 92
3 – It was narrated that Abu Hurayrah (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “If the people knew what there is in the call to prayer and the first row, and they had no other way but drawing lots, then they would draw lots.” Narrated by al-Bukhaari, 590; Muslim, 437.
The meaning of this hadeeth is that if the people knew what there is of great and abundant reward in the call to prayer and the first row, and they could not find any way to do the adhaan and determine who would stand in the front row except by drawing lots, then they would do that; they would draw lots in order to attain its virtue.
4 – It was narrated from al-Bara’ ibn ‘Aazib (may Allaah be pleased with him) that the Prophet of Allaah (peace and blessings of Allaah be upon him) said: “Allaah and His angels send blessings upon the front row, and the muezzin is forgiven as far as his voice reaches, and whatever hears him, animate or inanimate, confirms what he says, and he will have a reward like that of those who pray with him.” Narrated by al-Nasaa’i, 646; classed as saheeh by al-Mundhiri and al-Albaani, as it says in Saheeh al-Targheeb, 235.
With regard to the reward for the iqaamah, this is included in the ahaadeeth quoted above concerning the virtue of the adhaan, because the Prophet (peace and blessings of Allaah be upon him) called the iqaamah an “adhaan”, as in the hadeeth: “Between every two calls there should be a prayer.” Narrated by al-Bukhaari, 598; Muslim, 838.
Al-Haafiz said: The words “every two calls” mean the adhaan and iqaamah. End quote.
There is also a hadeeth which speaks specifically of the virtue of the iqaamah:
It was narrated from Ibn ‘Umar (may Allaah be pleased with him) that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Whoever gives the call to prayer for twelve years will be guaranteed Paradise, and for each day sixty hasanaat will be recorded for him by virtue of his adhaan, and thirty hasanaat by virtue of his iqaamah.” Narrated by Ibn Maajah, 728; classed as saheeh by al-Mundhiri and al-Albaani, as stated in Saheeh al-Targheeb, 248.
And Allaah knows best.
