سورة الحديد

The Prophet (peace be upon him and his family) — Irbad ibn Sariya said: The Noble Prophet (peace be upon him and his family) would always recite the Musabbihat (the surahs that begin with سبّح لله and یسبّح لله, namely: al-Hadid, al-Hashr, al-Saff, al-Jumu'ah and al-Taghabun) before going to sleep.

Imam Sadiq (peace be upon him and his family): Whoever recites Surah al-Hadid and Surah al-Mujadilah continually in an obligatory prayer, Allah will never punish him until he sleeps forever [dies], and he will never see any evil in himself or in his family, and he will find no illness in his body.

The Prophet (peace be upon him and his family): Whoever recites this surah, it is a right upon Allah that He keep him safe from His punishment and grant him blessings in His paradise; and whoever accustoms himself to reciting it, even if he is bound in chains and imprisoned, Allah will make his release from prison easy, even if he has committed many crimes.

The Prophet (peace be upon him and his family): Whoever recites Surah al-Hadid will be counted among those who believed in Allah and His Messengers.

Imam Baqir (peace be upon him): Whoever recites all the Musabbihat before sleeping will not die until he meets [sees] Imam al-Qa'im, and if he dies, he will be in the company of the Messenger of Allah (peace be upon him and his family).

The Prophet (peace be upon him and his family): Whoever writes it and hangs it upon himself, if he is in battle, no arrow and no iron will harm him, and he will be brave in battle; and if it is recited over a place in the body in which iron has become embedded, it will come out at once, without any pain.
