If a person recites this Surah ten times, one thousand sins of his are forgiven. If recited in compulsory prayers, all previous sins are forgiven. It is narrated from the Holy Prophet (Peace Be Upon Him) that reciting this Surah once carries the reward of fasting for the whole month of Ramadhan. Constant recitation of this Surah, increases sustenance.
If Surah Qadr is recited 11 times before sleeping, the reciter remains safe the whole night. Recitation in front of an enemy keeps one safe from his evil designs. For the paying back of loans, one should seek forgiveness and should recite Surah Qadr as many times as possible.
Imam Ja’far as-Sadiq (A.S) said that for pious children, one should keep his right hand on his wife and recite this Surah 7 times before going into her. If recited seven times on the grave of a believer, his sins will be forgiven.
