ভূমিকা
The blessed Chapter treats of the law of zihar, a kind of divorce in pre-Islamic times; positive and negative aspects of whispering; greeting with those entering a meeting; distinction of the party of God and that of Satan. The Merit of Reciting the Chapter Two traditions have been narrated from the Noble Prophet (S) and Imam Sadiq (as).
According to the former: "One who recites Surah al-Hadid and Surah al-Mujadila and reflects and acts upon them, will be regarded as a member of the party of God." The latter says: "One who recites Surah al-Hadid and Surah al-Mujadila in their obligatory prayers will neither be afflicted with any torment in his life, nor will he or his family suffer from evil, nor will he be entangled with poverty and destitute.” The contextual meaning of these Chapters is clearly consistent with the said rewards indicating that the goal of reciting them is to apply them in one's life rather than mere recitation devoid of reflecting and acting upon them.
There was a kind of divorce in pre-Islamic times called zihar as per which the husband was not allowed to revoke the divorce nor was the wife allowed to remarry. A certain man divorced his wife in this manner at the time of the Prophet of the Islamic faith (S) thus addressing her: "You are to me like my mother's back." The man came unto the Noble Prophet (S) and informed him of the case.
