[1] Iqamat-as-Salat: [the offering of Salat (prayers) perfectly]. It means that:

a) Each and every Muslim, male or female, is obliged to offer his Salât (prayers) regularly five times a day at the specified times; the male in a mosque in congregation and the female at home. As the Prophet (ﷺ) has said: "Order your children for Salât (prayers) at the age of seven and beat them (about it) at the age of ten." The chief (of a family, town, tribe, etc.) and the Muslim ruler of a country are held responsible before Allâh in case of non-fulfillment of this obligation by the Muslims under his authority.

b) One must offer the Salât (prayers) as the Prophet (ﷺ) used to offer them with all their rules and regulations i.e., standing, bowing, prostrating, sitting etc. As he has said: Offer your Salat (prayers) the way you see me offering them الا الم [For the characteristics of the Salat (prayer) of the Prophet (ﷺ) --- se Sahih al Bukhâri, Vol. 1.].
