Abu Hurairah (Ra) narrates: I heard Rasúlullãh (saw) saying: To be in the Path of Allãh, for a short while, is better than worshipping on the night of Al-Qadr in front of Hajaril-Aswad (the Black Stone).

(Ibne-Hibban)

Note: Worshipping on the Night of Al-Qadr is more virtuous then worshipping for a thousand months as mentioned in Suratul Qadr.
