Khutbah in the context of "Eid al-Adha"

Salah (Arabic: ٱلصَّلَاةُ, romanized: aṣ-Ṣalāh, also spelled Salat), also known as Namaz (Persian: نماز, romanized: namāz), is the practice of formal worship in Islam, consisting of a series of ritual prayers performed at prescribed times daily. These prayers, which consist of units known as rak'ah, include a specific set of physical postures, recitation from the Quran, and prayers from the Sunnah, and are performed while facing the direction towards the Kaaba in Mecca (qibla). The number of rak'ah varies depending on the specific prayer. Variations in practice are observed among adherents of different madhahib (schools of Islamic jurisprudence). The term salah may denote worship in general or specifically refer to the obligatory prayers performed by Muslims five times daily, or, in some traditions, three times daily.

The obligatory prayers play an integral role in the Islamic faith, and are regarded as the second and most important, after shahadah, of the Five Pillars of Islam for Sunnis, and one of the Ancillaries of the Faith for Shiites. In addition, supererogatory salah, such as Sunnah prayer and Nafl prayer, may be performed at any time, subject to certain restrictions. Wudu, an act of ritual purification, is required prior to performing salah. Prayers may be conducted individually or in congregation, with certain prayers, such as the Friday and Eid prayers, requiring a collective setting and a khutbah (sermon). Some concessions are made for Muslims who are physically unable to perform the salah in its original form, or are travelling.

A mosque (/mɒsk/ MOSK), also called a masjid (/ˈmæsdʒɪd, ˈmʌs-/ MASS-jid, MUSS-), is a place of worship for Muslims. The term usually refers to a covered building, but can be any place where Islamic prayers are performed; such as an outdoor courtyard.

Originally, mosques were simple places of prayer for the early Muslims, and may have been open spaces rather than elaborate buildings. In the first stage of Islamic architecture (650–750 CE), early mosques comprised open and closed covered spaces enclosed by walls, often with minarets, from which the Islamic call to prayer was issued on a daily basis. It is typical of mosque buildings to have a special ornamental niche (a mihrab) set into the wall in the direction of the city of Mecca (the qibla), which Muslims must face during prayer, as well as a facility for ritual cleansing (wudu). The pulpit (minbar), from which public sermons (khutbah) are delivered on the event of Friday prayer, was, in earlier times, characteristic of the central city mosque, but has since become common in smaller mosques. To varying degrees, mosque buildings are designed so that there are segregated spaces for men and women. This basic pattern of organization has assumed different forms depending on the region, period, and Islamic denomination.

A minbar (Arabic: منبر; sometimes romanized as mimber) is a pulpit in a mosque where the imam (leader of prayers) stands to deliver sermons (خطبة, khutbah). It is also used in other similar contexts, such as in a Husayniyya, where the speaker sits and lectures the congregation.
