سَلَامٌ هِيَ حَتَّى مَطْلَعِ الْفَجْرِ
“ (It is) peace, till the break of dawn”
Imam Sadiq (as) said, My father narrated for me that Ali bin Abi Talib (as) recited the verses in the Chapter of Qadr while Hasan and Husain (as) were with him.
Husain (as) said, O father! Hearing (this chapter) from your mouth tastes like something sweet.
Ameerul Momeneen (as) replied, O son of the Messenger of Allah (sawa) and O my son (as)! I know that which you do not know about this chapter. When this chapter was revealed, your grandfather, the Messenger of Allah (sawa), sent (someone) to call me. When I went to him), he recited this chapter for me.
Then he tapped my right shoulder and said: O my brother, my successor, my Wali on my nation after me, and the war against my enemies until the Day of Resurrection! This chapter is for you after me and it is for your children after you.
My brother from among the angels, Jibraeel, informed me about all of the affairs of my nation which will take place in this year. And I swear to Allah that he will inform you just as he informs the prophets. This (Night of Qadr) has a radiant light in your heart and the heart of your successors till the break of dawn on the day of the rising of the Qaem (as). (Taweel Al Ayat Al Zahirah page 794)
