Sunan Abi Dawud Book 2, Hadith 150
“Until you see me that I have come out”.
Abu dawud said: No one except Ma’mar has narrated the words “that I have come out”. And the version transmitted by Ibn ‘Uyainah from Ma’mar does not mention the words “that I have come out”.
the prophet (ﷺ) said; When the Iqamah for prayer is pronounced, do not stand until you see me.
Abu Dawud said: this has been narrated by Ayyub and Hajjaj al-Sawwaf from Yahya and Hisham al-Duatawa’i in a similar way, saying : Yahya wrote to me (in this way). And this has been narrated by Mu’awiyah b. Sallam and ‘Ali b. al-Mubarak from Yahya: “Until you see me and show tranquility”.
when the Iqamah was pronounced for prayer during the time of the Messenger of Allah (ﷺ), the people would take their seats before the prophet (ﷺ) came to his seat.
