Is it permissible to send blessings upon one who pays zakah, and what is the ruling on saying “peace and blessings be upon him” for anyone other than the Prophet?

The Shaykh : He asks: Is it permissible for the imam to send blessings upon one who has paid the zakah of his wealth, as in the verse? And what is your opinion regarding directing it to some people? Like some people saying, “May peace and blessings be upon the Mahdi.” What does that mean? Who is meant? Because the Mahdi will appear in the end times; he has not appeared and gone, and that is the end of it. How? We give charity. Fear. They have a divorce and that is the end of it. I mean, if… other than this extinct metal. Yes, I mean, if he pays his zakah, they say “Mahdi”? Yes. The first question.
We know the answer to the first question: it is permissible. If someone gives you his zakah, you may say, “O Allah, send blessings upon him,” as Allah the Exalted commanded His Prophet to do, and we have a precedent for this. But what does the second one mean? We do not know the second one. And what is your opinion regarding directing it? The sending of blessings. Yes, to some people, like some people saying, “May peace and blessings be upon the Mahdi.” Yes, we have this Mahdi, other than the expected Mahdi. Another person? Yes. He exists. No, he is finished. He died. Yes. It is finished. May Allah forgive us, even if he was extravagant. So what did he mean? They say the followers of the Mahdi now say, “May peace be upon the Mahdi.” The followers of the Mahdi now say to him, when he is mentioned among them, “May peace be upon the Mahdi.” It is directed to a specific person, right? The word “blessings” for a specific person. In directing it, meaning the zakah, meaning the sending of blessings, meaning the sending of blessings.
Yes, it is not deserved by him, like the hadith: it is permissible to say it for some people, like some people saying “Mahdi.” I mean, if this man whose name is Mahdi is mentioned, saying “peace and blessings be upon him” for him is not permissible, because if it is adopted as a title for a man other than the messengers, it places them in the position of the messengers. For this reason, we say that sending blessings upon anyone other than the prophets is permissible if it is incidental, as we say, “O Allah, send blessings upon Muhammad and upon the family of Muhammad.” And if it is said for a reason, such as giving zakah, it is also permissible. But if it is said without a reason and adopted as a title for a specific person, like one who says “Ali, peace be upon him” every time he says “Ali,” then this is wrong, because it places him in the position of the Messenger. Do you understand? And what is this “Hadi” that you have? Every time we mention Him, Glorified and Exalted is He, with “peace and blessings be upon him,” we have made him a prophet.
