Re: Tarawih questions
I believe that Taraweeh prayer is not compulsory, but something that is highly rewarded. The reason is that in Sahih Muslim and Bukhari, there are narrations ascribed to the Holy Prophet (pbuh) that seem to suggest that he did not make them compulsory on his nation. For instance:
"'A'isha reported that the Messenger of Allah (may peace be upon him) prayed one night in the mosque and people also prayed along with him. He then prayed on the following night and there were many persons. Then on the third or fourth night (many people) gathered there, but the Messenger of Allah (may peace be upon him) did not come out to them (for leading the Tarawih prayer). When it was morning he said: I saw what you were doing, but I desisted to come to you (and lead the prayer) for I feared that this prayer might become obligatory for you. (He the narrator) said: It was the month of Ramadan." (Sahih Muslim, Book 4, Number 1666)
Nonetheless, this prayer does contain a lot of rewards. However, since it is not compulsory and considered supregoratory (nafl), one can perhaps offer as many as they easily can - whatever brings them closer to God.
