Prayer

As we know, there are two main forms of Hebrew: Ashkenazi and Sefardi. And the most notable difference between them is the pronunciation of the last letter, the ת, as either an S or a T. Though the T-sound is considered Sefardi, I hear plenty of Ashkenazim using it. And I hear people who constantly switch around between the two, using them interchangeably, sometimes even in the same verse! (Example “YiTgadal V’YiSkadash”) How important is it to pronounce this letter according to one’s heritage? If one pronounces it differently from one’s family custom, is the prayer or blessing still valid? If a Torah reader pronounces it unlike his tradition, must he be corrected? How about if one suddenly decides to change because he joins a congregation that does it the other way or simply wants to?

Hi-- I'm trying to find out more about the Ana BaKoach prayer. I know it is traditionally said during Kabbalat Shabbat. Is there another place in our daily or weekly liturgy where I might find it? Do you know when it first appeared as a prayer? What else can you tell me about it? Thanks!

Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. Is it permitted on Shabbos to dry a kiddush cup with a piece of toilet paper, if one is not going to throw out the toilet paper afterwards but plans on using it after? Also, if one missed shacharis but was not o'nes (i.e., he was negligent) in missing it, on a day when mussaf and hallel are said, and the time for mincha has arrived, would he daven mincha first, and then hallel and then musaf, or in which order should he daven these prayers. Thanks a lot.
