Abd al-Rahman bin Ammar bin Sa'd al-Qaraz (who was the mu'adhdhin of the Messenger of Allah, peace and blessings be upon him) narrates from his father, and he from his grandfather, that: The Messenger of Allah (peace and blessings be upon him) commanded Sayyiduna Bilal (may Allah be pleased with him) to put his fingers in his ears (when giving the adhan), and said: "It makes your voice louder." And the phrases of the adhan of Sayyiduna Bilal (may Allah be pleased with him) were said twice each, and the phrases of the iqamah once each, while the words 'Qad qamatis-salah' (the prayer has been established) were said only once. And he used to give the adhan on Friday before the Messenger of Allah (peace and blessings be upon him) when the shadow was equal to a sandal strap (that is, right after the sun passed its zenith). And when the Messenger of Allah (peace and blessings be upon him) went out for the two Eids, he would pass by the way of the house of Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him), then pass by the people of the tents, then begin with the prayer before the sermon. Then in the first rak'ah he would say the takbir seven times before the recitation, and in the second rak'ah five times before the recitation. Then he would deliver the sermon to the people, then return by the other route, that is, the route of Banu Zurayq, and at the edge of the lane he would slaughter his sacrificial animal with his own hand with a knife. Then he would go towards the houses of Sayyiduna Ammar bin Yasir and Sayyiduna Abu Hurayrah (may Allah be pleased with them both) at the place called al-Balat. He (peace and blessings be upon him) would go to the two Eids on foot and return on foot. He would say the takbir in the pauses during the sermon, and would say the takbir abundantly in the sermon of the two Eids. When he delivered a sermon on the occasion of war, he would deliver it leaning on a bow, and when he delivered the Friday sermon, he would deliver it leaning on a staff. And when Sayyiduna Bilal (may Allah be pleased with him) said the takbir in the adhan, he would face the qiblah; then he would remain facing the qiblah while saying twice 'Allahu akbar, Allahu akbar' (Allah is the Greatest, Allah is the Greatest), twice 'Ashhadu an la ilaha illallah' (I bear witness that there is no god but Allah), and twice 'Ashhadu anna Muhammadan rasulullah' (I bear witness that Muhammad is the Messenger of Allah). Then he would turn from the qiblah to the right side and say twice 'Hayya 'ala al-salah' (Come to the prayer), then turn from the qiblah to the left side and say twice 'Hayya 'ala al-falah' (Come to success), then face the qiblah and say: 'Allahu akbar, Allahu akbar, la ilaha illallah' (Allah is the Greatest, Allah is the Greatest, there is no god but Allah).

It is narrated from Hafs bin Umar bin Sa'd al-Qaraz that his father and paternal uncles told him that: Sayyiduna Sa'd al-Qaraz (may Allah be pleased with him) was the mu'adhdhin of the people of Quba', then Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) moved him from there and appointed him as mu'adhdhin (in Madinah). (After this) is the honourable mention of Sayyiduna Junadah bin Abi Umayyah al-Azdi (may Allah be pleased with him).
