I heard the Prophet ﷺ say, "Lying about me is not like lying about anyone else. Whoever lies about me deliberately, let him take his seat in the Fire."And I heard the Prophet ﷺ say, "Whoever is wailed over will be punished according to what is wailed over him."
سمعت النبي ﷺ يقول: إن كذبا علي ليس ككذب على أحد، من كذب علي متعمدا فليتبوأ مقعده من النار وسمعت النبي ﷺ يقول: من نيح عليه يعذب بما نيح عليه.
Bukhari narrated it in the Book of Funerals (1291) and Muslim in the Book of Funerals (28:933), both from the hadith of Saeed bin Ubayd, from Ali bin Rabia, from Mughira bin Shuba, and he related it, with the wording being that of Bukhari. As for Muslim, he confined himself to the second part of the hadith.
