´It was narrated that Abu Al-Muthanna, the Mu'adhdhin of the Jami' Masjid, said:` "I asked Ibn 'Umar about the Adhan and he said: 'At the time of the Messenger of Allah (S.A.W), the phrases of the Adhan were recited twice and the phrases of Iqamah once, except that you should say (the phrase) Qad qamat is-salah (prayer is about to begin)twice. When we heard 'prayer is about to begin' we would perform Wudu' and go out to pray.'"
1؎: Some people would do this occasionally, yet due to the Prophet’s (sallallahu alayhi wa sallam) lengthy recitation, they would still catch the congregation.
Explanation & Benefits
Hafiz Muhammad Ameen
669. Commentary: This would have been an occasional occurrence, for example: due to eating or sleep; otherwise, the noble Companions (radi Allahu anhum) were usually present in the mosque beforehand. (For the discussion on the iqamah, see Hadith: 629 and the introduction of this very book.)

Narrated Abdullah ibn Umar: The words of adhan were pronounced from the time of the Messenger of Allah ﷺ twice in pairs (i. e. four times) each, and the words of iqamah were pronounced once in pairs (twice each), except that the phrase "The time for prayer has come" would be pronounced twice. When we heard iqamah, we would perform ablution, and go out for prayer. Shubah said: I did not hear Abu Jafar narrating any other tradition except this one.
Shaykh Umar Farooq Saeedi
510. Commentary: The noble Companions (radi Allahu anhum) would generally arrive at the mosque before the iqamah and wait for the prayer. However, if by chance someone was delayed, upon hearing the iqamah, he would quickly perform ablution (wudu) and come for the prayer.
