Surat al-Ḥujurat (سورة الحجرات‎, "The Chambers") is the 49 sura of the Quran

Sūrat al-Ḥujurāt (Arabic: سورة الحجرات‎, "The Chambers") is the 49th chapter (sura) of the Qur'an with 18 ayat. The chapter contains etiquette and norms to be observed in the Muslim community, including the proper conduct towards the prophet, an injunction against acting on news without verification, a call for peace and reconciliation, as well injunctions against defamation, suspicion, and backbiting. The chapter also declares a universal brotherhood among Muslims. The thirteenth verse, one of the most famous in the Quran, is understood by Muslim scholars to establish equality with regards to race and origin; only God can determine one's nobility based on his piety.

The chapter is a Medinan sura, revealed in the year 9 AH (630 CE) when the nascent Islamic state under the leadership of the prophet Muhammad had extended to most of Arabia. Muslim historians linked some of the verses (either verses 2–5 or just 4–5) to the conduct of a Banu Tamim delegation to Muhammad in Medina. The chapter reprimands the delegates' behaviour and then lays down protocol when interacting with Muhammad.
