Iqama

The iqama (إِقَامَة) is the second Islamic call to prayer, recited after the adhan. It summons those already in the mosque to line up for prayer (salah).

It is traditionally given a more rapid and less sonorous rendering than the adhan, as it is intended merely to draw the attention of those already in the mosque, rather than to remind those outside to come in. Most phrases of the iqama and adhan are the same, though there are variations among the schools (madhahib) of jurisprudence (fiqh) in the preferred number of repetitions of the phrases.

Text
The one unique line in the iqama, but not adhan, is qad qāmati ṣ-ṣalāh, the announcement "the prayer has been established", i.e., is about to commence. It is stated just before the opening allāhu akbar, the formal start of prayer.

The Hanafi and Shia schools both use the same number of repetitions in both the adhan and iqama, contrary to all the other schools.

Unlike the other schools, the Maliki school recommends qad qāmati ṣ-ṣalāh to be said only once. This is based on the practice of the people of Medina during Malik ibn Anas's time.

Other uses of the term iqama
Iqāma is the maṣdar form of the fourth (causative) stem (stem  ' af`ala) from the triliteral root Q-W-M, which relates to setting things up, carrying things out, existence, and assorted other meanings. The word iqāma itself is multivalent, but its most common meaning outside the inauguration of prayer is in the context of immigration law, referring to a long-term visa for a foreign national. In some cases, as in Egypt, it is a stamp on the foreigner's passport; in others (as in Morocco and Saudi Arabia) it is a separate identity document in the form of a plastic card.
