can he pray as much as he wants and then leave?.
Praise be to Allaah.
There is no doubt that Taraweeh is a Sunnah andis naafil; it is the
qiyaam of Ramadan. The same may be said of night prayers, Duha
(forenoon) prayer and the regular Sunnah prayers that are offered
along with the obligatory prayers. All of them are naafil, so he may
do them if he wants or not do them if he wants, but doing them is
better.
If he starts to pray Taraweeh with the imam and wants to leave
beforecompleting it, there is nothing wrong with that, but staying
with the imam until he finishes is better, and it will be recorded for
him as if he spent this night in prayer, because the Prophet
(blessings and peace of Allah be upon him) said: "Whoever prays qiyaam
with the imam until he finishes, Allah will record for him the qiyaam
of onenight." So if he stays with the imam until he completes it, he
will have attained the virtue of spending the whole night in prayer,
but if he leaves after praying some rak'ahs, there is nothing wrong
with that and no sin, because it is naafil. End quote.
