Bismillah
More on the same theme, for instance when the Messenger salla Allah a`lyhee wa sallam stated about one who spends layaltu alqadr praying, he said whoever stood for the prayers in the night of Qadr, which in Arabic could be better transalted as one who stays up all night of layalatu lqadr. Probably this one would be praying as the whole point is to stay up to pray. how many Raka`s do u think u can make during a whole night, i mean the whole night...? up to each one's capacity. That is why there are these varied numbers and Allah Knows best
