Question: Whoever prays the taraaweeh [prayers] must he then continue to pray them throughout Ramadhaan?
Response: No! He does not have to continue [to pray them] because it is a recommended (Sunnah) prayer in that if he prays them then he is rewarded and if he leaves them then he is not a sinner, however [in leaving them] he misses out on a lot of good as we have said [before].
