When should performers of the prayer – in the Masjid – stand up to join the rows

In The Name of Allah, The Most Merciful, The Bestower of Mercy. 

Al-Allamah Abdul Muhsin Al-Abbad, may Allah preserve him, stated:

Should they stand up at the beginning of the Iqama, at the end or when (they hear) Qad qama a-salaah [i.e. the prayer is about to begin]? Al-Hafidh Ibn Hajar, may Allah have mercy upon him, transmitted three statements in Al-Fath 2/120, however what is more evident is that the performers of the prayer should stand up when they hear the beginning of the Iqaamah in order to get ready and straighten the rows for the prayer.

It is reported in Sahih Muslim from Abu Hurairah, may Allah be pleased with him, who said: “The Iqaamah for the prayer would be called for Allah’s Messenger, peace and blessings of Allah be upon him, and the people would form rows before the Prophet stood up.” [Sahih Muslim 1369]

However, if the Imam is in the Masjid, the performers of the prayer should stand up when the Iqamah for the prayer is made and they see him enter the Masjid because of the Prophet’s  statement: “When the Iqamah is called for the prayer, do not stand up until you see me”. [Sahih Al-Bukhari 637 & Sahih Muslim 1365]

In another wording (of this hadith) in Sahih Muslim “Until you see that I have come out”. [Sahih Muslim 1366]
