It was narrated from Muhammed bin 'Abdullah bin Zaid that his father said that:
The Messenger of Allah was thinking of a horn, and he commanded that a bell be made and it was done. Then 'Abdullah bin Zaid had a dream. He said: "I saw a man wearing two green garments, carrying a bell. I said to him, 'O slave of Allah, will you sell the bell?' He said; 'What will you do with it?' I said, 'I will call (the people) to prayer.' He said, 'Shall I not tell you of something better than that?' I said, 'What is it?' he said, 'Say: Allahu Akbar Allahu Akbar, Allahu Akbar Allahu Akbar; Ash-hadu an la ilaha illallah, Ash-hadu an la ilaha illallah; Ash-hadu anna Muhammadan Messenger of Allah, Ash-hadu anna Muhammadan Messenger of Allah; Hayya 'alas-salah, Hayya 'alas-salah; Hayya 'alal-falah, Hayya 'alal-falah; Allahu Akbar Allahu Akbar; La ilaha illallah (Allah is The Most Great, Allah is The Most Great; Allah is The Most Great, Allah is The Most Great; I bear witness that none has the right to be worshipped but Allah, I bear witness that none has the right to be worshipped but Allah; I bear witness that Muhammed is the Messenger of Allah, I bear witness that Muhammed is the Messenger of Allah; Come to the Prayer, Come to the Prayer; Come to the prosperity, Come to the prosperity; Allah is the Most great, Allah is the Most Great; None has the right to be worshipped but Allah)." 'Abdullah bin Zaid went out and came to the Messenger of Allah, and told him what he had seen. He said, "O Messenger of Allah, I saw a man wearing two green garments carrying a bell," and he told him the story. The Messenger of Allah said, "Your companion has had a dream. Go out with Bilal to the mosque and teach it to him, for he has a louder voice than you." I ('Abdullah) went out with Bilal to the mosque, and I started teaching him the words and he was calling them out. 'Umar Al-Khattab heard the voice and came out saying, "O Messenger of Allah! By Allah, I saw the same (dream) as him."

Abu 'Ubaid said: "Abu Bakr Al-Hakami told me that 'Abdullah bin Zaid Al-Ansari said concerning that: 'I praise Allah, the Possessor of majesty and honor, A great deal of praise for the Adhan. Since the news of it came to me from Allah, So due to it, I was honored by the information. During the three nights. Each of which increased me in honor.'"
