Mughira reported,

Ali said, "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.'I also heard the Prophet ﷺ say, 'Whoever is wailed over will be punished on account of the wailing done over him.'"

Sahih

عن المغيرة قال

سمعت النبي ﷺ يقول: إن كذبا علي ليس ككذب على أحد، من كذب علي متعمدا فليتبوأ مقعده من النار سمعت النبي ﷺ يقول: من نيح عليه يعذب بما نيح عليه.
