How does one pay the zakah on his date palms if he has many, some of which are excellent and some are poor?

The questioner : If a person has many date palms, O Shaykh. Yes. Of different varieties. Some are expensive and some are cheap. Yes. Because some of the dates now go for two hundred, and some go for twenty riyals. Yes. And I pay the zakah on the poor ones, O Shaykh. Is that permissible, or does he pay the zakah on the expensive ones and pay the zakah on everything that reaches the nisab, the expensive ones?

The Shaykh : Have you not read the Qur'an? It is not permissible, but from where does it come out?
It is either that he gives it from the good dates willingly, and that is good, may Allah reward him with good, , or he spends from the bad ones, and that is not permissible, or he gives from the middle, and that is permissible, but designating the middle is very difficult because one must estimate the entire date crop, and one must know that the middle is, for example, one-third of the property, and this is difficult. For this reason, I see that he estimates the value of the entire date crop, the total value of the dates, and then he gives either in money or in dates equal to that value. Do you understand?
This is necessary, because in reality, as Salim mentioned, some of the dates, meaning the containers, are worth two hundred, and some are worth less, and we heard in the beginning when people were ignorant.
That they would pass by the date palms and a palm would be overbearing, not drinking much, and poor, and they would say, "Leave this for the zakah," explicitly saying, "Leave this for the zakah." This is not permissible.
