The most important thing for you to learn, as a new Muslim, is not how to wear hijab, and not how to speak Arabic, and not where to buy halal meats. It isn't to learn how to tell others about Islam, or to change your name to an Arabic name, or to get married. No. The most important piece of advice that we at I Profess.com, and I personally, can impart to you is that you learn how to do your required, or fardh, prescribed prayers, or salat (Salat-ul-Fardh). It is the first thing that you should learn, and the thing you should be most eager to accomplish as a Muslim.
