People standing when the iqamah is called before the imam comes

It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When the iqamah is called for the prayer, do not stand up until you see me."

Abu Khalid al-Walibi said: After the iqamah had been called for the prayer, Sayyiduna Ali (may Allah be pleased with him) came out, and the people were standing, waiting for him. Sayyiduna Ali (may Allah be pleased with him) said to them: "Why are you standing with your heads raised like heedless people?!"

Ibrahim said: The early generations used to dislike that, when the muezzin says "Qad qamat al-salah" (the prayer has been established), the people should stand up while the imam is not present, and that they should wait for the imam standing. And it used to be said that standing in this way is the standing of heedlessness.

Al-Zubayr bin Adi said: I asked Ibrahim: "Should the people wait for the imam standing or sitting?" He said: "Sitting."

Ibrahim said about people who wait for the imam standing: This is the standing of heedlessness.
