Zakah on palm trees

Q: I own many types of palm trees that vary in quality; including Rabi`ah, Ke`imez, and the best of which is called Barny. I pay Zakah (obligatory charity) from the best types of dates except the super kind of date (Barny) which I do not use to pay Zakah from. Some knowledge seekers told me that it is obligatory for me to pay Zakah from the most excellent type (Barny) along with other types. (Part No. 8; Page No. 52

A: Your duty is to pay Zakah on your palm trees when they reach the Nisab (the minimum amount on which Zakah is due) or more. You also have to pay from the average dates, although if you pay Zakah from every type, it will be better.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
