Assalam-o-Alaikum. 1. Can someone give a list of all obligatory and recommended Islamic financial dues (Khums, Zakat, Fitrah, etc)? 2. If possible, provide a comprehensive but straightforward explanation on what it is and how it should be paid (for each). I don't know if the Maraaji' differ regarding them, but in case they do, I would like Khamenei's rulings. JazakAllah.
