Laylatul-Qadr is the night, which is the best night among the nights of the whole year. The "A'maal" (religious performances) of this night are better than the A'maal of 1000 months. In this night the divine Annual Decree is passed. The Angels and Roohul Ameen (A highly dignified Angel) descend on this earth, in that night. These call on the Imam of the time, and what is ordained (by Allah) for everybody is presented before the Imam.
The twenty-third night of Ramadhan, the last of the Qadr Nights, is more meritorious than the 19th & 21st & many narrations confirm that it is the Qadr Night at which all affairs are decided.
In addition to the General a'amal at all the three Qadr Nights, there are other specific additional a'amal for the 23rd night:
1. Recite Surahs of al-`Ankabut (No. 29) and al-Rum (No. 30). Imam al-Sadiq (a.s) is reported to have said, “Anyone who recites these two Surahs at this night will be included with the people of Paradise.” Recite Surah of al-Dukhan (No. 44).
