Musannaf Ibn Abi Shayba 2:2

Abu Bakr narrated to us, he said: Affan narrated to us, Hammam ibn Yahya narrated to us, from Amir al-Ahwal, that Makhul narrated to him, that Abdullah ibn Muhayriz narrated to him, that Abu Mahdhura narrated to him, he said: The Prophet, may Allah bless him and grant him peace, taught me the Adhan as nineteen words, and the Iqamah as seventeen words. The Adhan: Allah is the Greatest, Allah is the Greatest, Allah is the Greatest, Allah is the Greatest. I bear witness that there is no god but Allah, I bear witness that there is no god but Allah. I bear witness that Muhammad is the Messenger of Allah, I bear witness that Muhammad is the Messenger of Allah. I bear witness that there is no god but Allah, I bear witness that there is no god but Allah. I bear witness that Muhammad is the Messenger of Allah, I bear witness that Muhammad is the Messenger of Allah. Come to prayer, come to prayer. Come to success, come to success. Allah is the Greatest, Allah is the Greatest. There is no god but Allah. And the Iqamah: Allah is the Greatest, Allah is the Greatest, Allah is the Greatest, Allah is the Greatest. I bear witness that there is no god but Allah, I bear witness that there is no god but Allah. I bear witness that Muhammad is the Messenger of Allah, I bear witness that Muhammad is the Messenger of Allah. Come to prayer, come to prayer. Come to success, come to success. The prayer has begun, the prayer has begun. Allah is the Greatest, Allah is the Greatest. There is no god but Allah.
