Al-Ahzab (Arabic: الأحزاب‎, al-aḥzāb;[1] meaning: the confederates,[2] or "the clans", "the coalition", or "the combined forces") is the 33rd chapter of the Quran with 73 verses. The sūrah takes its name from the mention of the parties (al-aḥzāb), or confederates (an alliance among the Quraysh and other tribes), who fought the Muslims at the Battle of the Trench (5/627), also known as the Battle of the Parties and as the siege of Madinah.[3]

This surah mentions what happened at the Battle of the Trench to remind believers the mercy and power of Allah since Allah made the various tribes who attacked Medina leave.

Regarding the timing and contextual background of the believed revelation (asbāb al-nuzūl), Q33 is a later period "Medinan surah". It contains instructions regarding the treatment of the Prophet and his wives and warns the hypocrites of their bad behavior.[5] According to some scholars, Medinan verses are concerned with the legal matters in Islamic society.[6] These suras generally contain rules and regulations for the believers to follow

In verses 56-57 warning was given to stop criticizing the Holy Prophet's marriage and his domestic life, and the believers instructed not to indulge in fault-finding like the enemies of Islam, but to invoke the blessings of Allah for their Prophet; moreover, they were instructed that they should avoid falsely accusing one another even among themselves, not to speak of the person of the Prophet.

In verse 59 the third step for social reform was taken. All the Muslim women were commanded that they should come out well covered with the outer garments and covering their faces whenever they came out of their houses for a genuine need.
