al-Ahzab
The Messenger of Allah (pbuh) has said the following about this Chapter: "Whoever reads it and teaches it to his family and those whom his right hand possesses, will be granted security against the torment of the grave." Imam Ja'fer al-Sadiq (as) has said that one who reads it quite often will, on the Day of Judgment, be in the neighborhood of the Prophet (pbuh).
