The Prophet ﷺ said, "Do not curse one another with the curse of Allah, nor with the wrath of Allah, nor with the Fire."
عن النبي ﷺ قال: لا تلاعنوا بلعنة الله ولا بغضب الله، ولا بالنار.
Narrated by Abu Dawud (4906), Tirmidhi (1976), Ahmad (20175), and Bukhari in Adab al-Mufrad (320), and Hakim graded it sahih (1/48), all of them through various routes from Qatada, from Hasan, from Samura, who said, then he related it.Its isnad is sahih. Tirmidhi said, "This is a hasan sahih hadith." Hasan here is Ibn Abu Hasan Basri, who was known to conceal defects in his chains of transmission, and he transmitted this using the ambiguous wording "from," but his hearing directly from Samura is sahih and firmly established.
