The whole of Ramadhān was a spiritual tournament and the night of 'Īd (i.e. the night before 'Īd day) is when the winning team is awarded their prize.
If you are given the ability to worship Allāh ta'ālā during this auspicious night then it is an indication that you are in the winning team.
In order to be eligible for a prize the least we should do is to refrain from every sin and engage in a little bit of extra 'ibādah for a while during this night.
