Sayyiduna Anas (may Allah be pleased with him) narrates that it is Sunnah that when the muezzin says «‏‏‏‏حَيَّ عَلَى الْفَلَاحِ» ‏‏‏‏ in the Fajr adhan, he should say « اَلصَّلٰوۃُ خَیْرٌ مِّنَ النَّوْم» ‏‏‏‏ "Prayer is better than sleep."

And the explanation of the evidence that the muezzin will turn only with his mouth, not with his whole body, and turning with the mouth is possible by turning the face.

Sayyiduna Abu Juhaifah (may Allah be pleased with him) narrates that I saw Sayyiduna Bilal (may Allah be pleased with him) giving the adhan, and he was turning his mouth (to the right and left). Sufyan described its manner and said that he was turning his head to the right and left. Sayyiduna Abu Juhaifah (may Allah be pleased with him) narrates that I presented myself before the Prophet (peace and blessings be upon him) at the place of Batha while he (peace and blessings be upon him) was sitting in a red tent and there were only a few people with him. Then Sayyiduna Bilal (may Allah be pleased with him) came and gave the adhan, then while saying «‏‏‏‏حَيَّ عَلَى الصَّلَاةِ، حَيَّ عَلَى الْفَلَاحِ» ‏‏‏‏, he turned his face to the right and left. In this narration, Thawri says that while saying «‏‏‏‏حَيَّ عَلَى الْفَلَاحِ» ‏‏‏‏ in his adhan, he turned his head to the right and left.

Provided that the hadith is authentic, because I have preserved these words only from Hajjaj bin Arta’ah. And I do not know whether Hajjaj heard this hadith from ‘Awn bin Abi Juhaifah or not. Therefore, I doubt the authenticity of this hadith due to this reason.

Sayyiduna Abu Juhaifah (may Allah be pleased with him) narrates that I saw Sayyiduna Bilal (may Allah be pleased with him) giving the adhan with both his fingers inserted in his ears, and during his adhan, he would turn to the right and to the left (that is, while saying «‏‏‏‏حَيَّ عَلَى الصَّلَاةِ» ‏‏‏‏ and «‏‏‏‏حَيَّ عَلَى الْفَلَاحِ» ‏‏‏‏).

Abdur Rahman bin Abi Sa’sa’ah narrates from Sayyiduna Abu Sa’id (may Allah be pleased with him) that he said: When you are in the wilderness, give the adhan (call to prayer) in a loud voice, because I heard the Messenger of Allah (peace and blessings be upon him) say:“Whatever tree, clod of earth, stone, jinn, or human hears the voice of the mu’adhdhin (caller to prayer), they will bear witness for him.”Marrah says that Abdullah bin Abdur Rahman Abi Sa’sa’ah narrated this hadith to me; he says that my father narrated this hadith to me, and he was an orphan under the care of Sayyiduna Abu Sa’id (may Allah be pleased with him), while his mother was with Sayyiduna Abu Sa’id (may Allah be pleased with him) as his wife.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "The sins of the muezzin are forgiven up to the extent his voice reaches. And every fresh and dry thing will bear witness for him. And for the one who attends the (congregational) prayer, twenty-five good deeds are written for him and the sins between the two prayers are forgiven for him." Imam Abu Bakr (may Allah have mercy on him) says that by «‏‏‏‏بينهما» ‏‏‏‏ he means the sins between the two prayers.

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "If people knew what reward and virtue there is in calling the Adhan and performing prayer in the first row, and they found no way except to draw lots, then they would draw lots for it." This is the hadith of Yahya bin Hakim. Utbah bin Abdullah Yahmadi says that I recited this hadith from Sumi to Imam Malik.

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "When Satan hears the call to prayer (adhan) for the prayer, he turns his back and flees while passing wind, so that he does not hear the adhan."

Sayyiduna Jabir (may Allah be pleased with him) narrates that I heard the Messenger of Allah (peace and blessings be upon him) say: "When Satan hears the call to prayer for Salah, he goes away until he reaches the place of Rauha." Sulaiman says that I asked (my respected teacher Abu Sufyan), "Where is Rauha?" He replied, "It is at a distance of thirty-six miles from Madinah Munawwarah."
