Al-Ahzab (Arabic: الأحزاب‎, "The Clans, The Coalition, The Combined Forces") is the 33rd chapter (sūrah) of the Quran (Q33) with 73 verses (āyāt). The surah (Surat / Sorah / Sura / Sorat) 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.

Exegesis:
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 / Madani / Madni surah". It contains instructions regarding treatment of the Prophet and his wives and warns the hypocrites of their bad behavior. According to some scholars, Medinan verses are concerned with the legal matters in Islamic society. These suras generally contain rules and regulations for the believers to follow.

Verses 33:5-6 are concerned with the differences between adopted and blood-related persons. Verse 33:5 refers to adoption in Islam and verse 33:6 contains a reference to the term Mother of Believers, who were Prophet's wives. This perhaps suggests their elevated standing with the community and in the later verses, these women are described as "unlike any other."

Verses 33:7-8 show that God will test even the sincerity of the prophets. The beginning of the sura seems to be concerned with truthfulness. The sura reinforces that "God is enough to trust...All this is written in the Scripture...God will question [even] the truthful about their sincerity, and for those who reject the truth He has prepared a painful torment...speak in a direct fashion." Truthfulness and trust seem to be emphasized for believers and Muhammad since he was dealing with hypocrites and betrayers[according to whom?] in Medina, who spread lies, deserted the army during the battle, or supported the attackers.

Verses 33:9-27 are concerned with the believers and hypocrites' reactions to the Battle of the Trench. The believers are those who remain steadfast in their belief and courage whereas the hypocrites try to run for safety, abandon the Muslim army, and doubt God and Prophet Muhammad (PBUH).

Ye have indeed in the Apostle of God a beautiful pattern (of conduct) for any one whose hope is in God and the Final Day, and who engages much in the Praise of God. Translation Yusuf Ali (Orig. 1938)

In the commentary of Majma’ul Bayan it is narrated from the Holy Prophet (S) that whoever recites Surah al-Ahzab and also teaches it to his family members, he will be saved from the torment of the grave.

Imam Ja’far as-Sadiq (a.s.) has said that the reward for reciting this Surah often is countless and the one who does so will be under the protection of the Holy Prophet (S) and his progeny on the Day of Reckoning. Keeping this Surah written (on deer-skin) makes a person honourable in the eyes of people, and everyone craves for his company.

Reward of reciting Surah Ahzab
1. Imam Sadiq (a.s.) said: One who recites Surat Ahzab extensively and teaches it to his family and servants, will be given protection against the chastisement of the grave.
