It has been reported from the Holy Prophet (peace and blessing be upon his family): Whoever recites on the tenth night of Sha'ban, a 4 (2x2) Raka' prayer, reciting in each unit Surah Fatiha once and Surah Ayatul Kursi once and Surah Kawthar three times.
Allah would tell the angels, 'Record one-hundred thousand good deeds for him, raise his rank one-hundred thousand levels, and open the ways of one-hundred thousand doors.'
