Albdullah bin Zaid narrated:"When we awoke, we went to Allah's Messenger to inform him of the dream. He said: 'Indeed this dream is true. So go to Bilal, for he has a better and louder voice than you. Convey to him what was said to you, so that he may call (to the prayer) with that.'" He said: "When Umar bin Al-Khattab heard Bilal calling for the prayer he went to Allah's Messenger, and he was dragging his Izar, (as he was hurrying) saying: 'O Allah's Messenger! By the One Who sent you with the truth! I dreamt the same as what he said.''' He said: "So Allah's Messenger said: 'To Allah is the praise, so that confirms it even more
Ibn Umar narrated:"When the Muslims arrived in AI-Madinah, they used to assemble for the Salat, and guess the time for it there was no one who called for it (the prayer). One day they discussed that and some of them said that they should use a bell like the bell the Christians use. Others said they should use a trumpet like the horn the Jews use. But Umar [bin Al-Khattab] said: 'Wouldn't it better if we had a man call for the prayer?'" He said: "So Allah's Messenger said: 'O Bilal! Stand up and call for the Salat
Abu Mahdhurah narrated that :Allah's Messenger sat with him and taught him the Adhan word for word. Ibrahim said, "It is the same as our Adhan." Bishr said: "So I said to him, 'Repeat it to me.' So he described the Adhan with At-Tarjl
Jabir [bin Abdullah] narrated:"Allah's Messenger said to Bilal: "O Bilal! When you call the Adhan then do so deliberately and slowly, and when you call the Iqamah then be quick. Allow enough time between your Adhan and Iqamah for the person eating to finish what he is eating, the person drinking to finish what he is drinking, and the one who needs time to relive himself, and do not stand until you see me
Abu Juhaifah narrated:"I saw Bilal calling the Adhan, and turning, and his (face) was following here and there, and his (index) fingers were in his ears, and Allah's Messenger was in a small red tent" - "I think," he (one of the narrators) said, "it was made from a hide" - so Bilal went out in front of him with an Anazah which he planted (in the ground) at Batha. Allah's Messenger prayed facing it, and a dog and a donkey passed in front of him; he was wearing a red Hullah, and it is as if I am now looking at the radiance of his shins." Sufyan said: "We think that it was a Hibrah
Bilal narrated:"Allah's Messenger said [to me]: 'Do not say the Tathwib for any prayer except the Fajr prayer.'" [He said:] There is something on this topic from Abu Mahdhurah. Abu `Eisa said: We do not know of the Hadith of Bilal except as a narration of Abu Isra'il Al-Mula'i. Abu Isra'il did not hear this Hadith from Al-Hakam bin `Utaibah. He said: He only reported it from Al-Hasan bin `Umarah, from Al-Hakam bin `Utaibah. Abu Isra'il's name is [Isma`il bin Abi Ishaq, and he is not strong according to the people of Hadith. The people of knowledge have differed over the interpretation of At-Tathwib. Some of them say that At-Tathwib is when one says "As-Salatu Khairummin An-Nawm, (prayer is better than sleep)" for the Adhan of Fajr. This is the saying of Ibn Al-Mubarak and Ahmad. Ishaq said something different about At-Tathwib, he said: "[The disliked Tathwib] is something that the people started after the Prophet; when the Mu'adh-dhin calls the Adhan and the people are slow in coming, so between the Adhan and the Iqamah he says: 'Qad Qamatis-Salat, Hayya `Alasalat, Hayya `AlalFalah. (Prayer is ready, come to prayer, come to success.)" [He said:] This Tathwib, which Ishaq mentioned, is the one that the people of knowledge dislike, which they innovated after the Prophet. But Ibn Al-Mubarak and Ahmad explained that At-Tathwib is when the Mu'adh-dhin says: "As-Salatu Khairum minan-Nawm, (prayer is better than sleep)" for the Adhan of Fajr. And this is the correct saying, and it is called At-Tathawwub as well, and this is the one chosen by the people of knowledge, and it is their opinion. It has been reported from `Abdullah bin `Umar that he would say: "As-Salatu Khairum-minan-Nawm, (prayer is better than sleep)" for Fajr. It has been reported from Mujahid that he said: "I entered a Masjid with `Abdullah bin `Umar in which the Adhan was called, and we wanted to pray in it. Then the Mu'adh-dhin said the Tathwib. So `Abdullah bin `Umar left the Masjid and said: 'Let us leave the place of this innovator' And he did not pray in it." [He said:] `Abdullah only disliked the Tathwib that the people invented later on
