When the imam says the takbir once the muezzin says: qad qamat al-salah

Imran bin Muslim said: When the muezzin said "Qad qamat al-salah" (the prayer has been established), Suwayd bin Ghafalah would say the takbir at that point.

Isma'il bin Abi Khalid said: When the muezzin said "Qad qamat al-salah" (the prayer has been established), meaning the first time, Qays would say the takbir at that point.

Mughirah said: Even after Ibrahim had said the takbir, I could still hear the voice of the muezzin.

Ibrahim said: If the imam wishes, he may say the takbir when the muezzin says "Qad qamat al-salah" (the prayer has been established), and if he wishes, he may say the takbir after the iqamah has been completed.

Muhill said: When the muezzin said "Qad qamat al-salah" (the prayer has been established) the second time, Ibrahim would say the opening takbir (takbir al-tahrimah).

Hisham said: Al-Hasan considered it disliked for the imam to stand up before the muezzin says "Qad qamat al-salah" (the prayer has been established), and he also considered it disliked for him to say the opening takbir before the iqamah is completed.

Abu Ma'shar said: It was Ibrahim's practice that when the muezzin said "Hayya ala al-salah" (come to prayer), he would stand up, and when he said "Qad qamat al-salah" (the prayer has been established), he would say the opening takbir.

Al-A'mash said: It was the practice of Yahya bin Waththab to remain silent while the muezzin was saying the iqamah, and when he finished, he would say the opening takbir. Ibrahim, on the other hand, would say the takbir when the muezzin said "Qad qamat al-salah" (the prayer has been established).
