سورة القدر

The Messenger of Allah (peace be upon him and his family): On the Night of Qadr, Satan is not released [from his bonds] until the dawn of that night breaks; and Satan on that night cannot afflict anyone with ruin, sickness or any kind of corruption, and no sorcerer's magic takes effect on that night.

Imam Sajjad (peace be upon him): سَلامٌ هِیَ حَتَّی مَطْلَعِ الْفَجْرِ [Peace! it is till the break of the morning]; Allah says: O Muhammad (peace be upon him and his family)! My angels and Jibreel, from the beginning of their descent until the rising of dawn, bring you My greeting of peace.

Imam Sajjad (peace be upon him): That night is the greeting of peace [from the angels] [upon those who stand for prayer or are in ruku' and sujud, or it is a night of safety and freedom from the harm of the satans], whose blessing and goodness continues until the appearance of the light of dawn, and is lasting and perpetual.

Imam Sadiq (peace be upon him): تَنَزَّلُ الْمَلائِکَةُ وَ الرُّوحُ فِیها بِإِذْنِ رَبِّهِمْ [The angels and the Spirit descend therein by the permission of their Lord] means, from their Lord upon Muhammad (peace be upon him and his family) and the family of Muhammad (peace be upon them) concerning every affair, [it is] peace.

Imam Sadiq (peace be upon him): حَتَّی مَطْلَعِ الْفَجْرِ [till the break of the morning]; meaning the Night of Qadr, [a night filled with peace [and blessing and mercy] until the break of dawn].

Imam Sadiq (peace be upon him): حَتَّی مَطْلَعِ الْفَجْرِ [till the break of the morning]; meaning until Hazrat al-Qa'im (may Allah hasten his noble reappearance) rises up.
