Al-Hujurat الحُجُرات

Al-Hujurat ( الحُجُرات,  meaning: The Chambers) is the 49th chapter of the Quran with 18 verses. The chapter contains etiquette and norms to be observed in the Muslim community, including the proper conduct towards the Islamic prophet, Muhammad, an injunction against acting on news without verification, a call for peace and reconciliation, as well as 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 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' behavior and then lays down protocol when interacting with Muhammad.

Proper conduct towards Muhammad

Verses 1 to 5 focus on the etiquette towards Muhammad, including lowering one's tone in his presence and respecting the privacy of his chambers.[2][3]

The following verses (6—12) emphasise the ties of brotherhood within the Muslim community (ummah) and establish social principles to maintain its unity.[2] Verses 6 to 8 call on Muslims to not act on news before verifying its authenticity.[4] The following two verses encourage promoting peace and reconciling quarreling parties within the community.[5] The tenth verse is known as the Verse of Brotherhood and instructs Muslims to unite in a universal brotherhood.[6] The next verse, verse 11, warns the members of the community against defamation, mocking and name-calling.[7] Verse 12 calls for Muslims to avoid suspicion (zann, also translated "conjecture"), spying on others to find faults (tajassus), and backbiting (ghibah).[8][9] The Quran considers backbiting (slandering someone in their absence) so sinful and abhorrent that it is compared to "eating the flesh of [one's] brother".[10]

Verse 13 is one of the most famous verses of the Quran:

O mankind, surely We have created you from a male and a female, and made you tribes and families that you may know each other. Surely the noblest of you with Allah is the most dutiful of you. Surely Allah is Knowing, Aware.[11]

Commentators on the Quran, including Abul A'la Maududi and Sayyid Qutb, argued that this verse declares the equality of mankind. Mankind is spread around the world and has different nations and tribes to know each other, and no one is superior based on color, race, or origin. According to the verse, only taqwa (piety, fear of God) makes one nobler before God.[12][13] According to the commentary of The Study Quran, this verse marked a reform of the moral order in Arabia, where previously one's worth had been determined by "lineage and grandiose displays of valor and generosity" and where fear of God had been seen as the opposite of nobility, to one which focused on "the depth of faith and piety".[13]

The remaining verses (14 to 18) contain clarifications on the Quranic view of faith[2] 

Verse 14 indicates degrees of faith: Islam (submission) and the higher iman (belief).[14] 

According to verse 15, a true believer believes in God and Muhammad without doubt, and proves it through devotion and the spending of one's wealth in the way of God.[15][16] The chapter closes by saying that only God knows the real extent of one's faith

The chapter is named after the word Al-Hujurat (The Private Apartments) which appeared in the fourth verse

Verses 4 and 5 instructed the Muslims to not enter the private apartments of Muhammad—at this pointthe ruler of most of Arabia —or his wives to search for or petition him
