3. Two variants have been transmitted for its wording:

The first variant contains seventeen words:
Allāhu Akbar (Allah is the Greatest) 1, Allāhu Akbar 2, Allāhu Akbar 3, Allāhu Akbar 4; ash-hadu an lā ilāha illā Allāh (I bear witness that there is no god but Allah) 5, ash-hadu an lā ilāha illā Allāh 6; ash-hadu anna Muḥammadan Rasūl Allāh (I bear witness that Muḥammad is the Messenger of Allah) 7, ash-hadu anna Muḥammadan Rasūl Allāh 8; ḥayya ʿalaṣ-ṣalāh (Come to prayer) 9, ḥayya ʿalaṣ-ṣalāh 10; ḥayya ʿalal-falāḥ (Come to success) 11, ḥayya ʿalal-falāḥ 12; qad qāmat aṣ-ṣalāh (The prayer is about to begin) 13, qad qāmat aṣ-ṣalāh 14; Allāhu Akbar 15, Allāhu Akbar 16; lā ilāha illā Allāh (There is no god but Allah) 17.

There are several ḥadiths on this point:

1. Abū Maḥdhūra reported that the Prophet ﷺ taught him the adhān as nineteen words and the iqāma as seventeen words. In the wording preserved by Ibn Khuzayma in his Ṣaḥīḥ it states: “He taught him the adhān and the iqāma, two by two.”

This ḥadith is authentic, and its full documentation has already been given under Issue Four of the chapter on the adhān. Al-Dāraquṭnī added at the end: “He does not return from that point.”

I say: meaning he does not repeat anything in the iqāma.

2. ʿAbd al-Raḥmān ibn Abī Laylā related: The Companions of Muḥammad ﷺ told us that ʿAbd Allāh ibn Zayd al-Anṣārī came to the Messenger of Allah ﷺ and said, “O Messenger of Allah, I saw in a dream a man wearing two green garments who stood on a wall, called the adhān, reciting each phrase twice, and then gave the iqāma in the same manner, reciting each phrase twice.”
