Cursing one another with the curse of Allah, with the anger of Allah, and with the Fire Al-Adab Al-Mufrad 320
Arabic hadith text
حَدَّثَنَا مُسْلِمٌ، قَالَ: حَدَّثَنَا هِشَامٌ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، عَنْ سَمُرَةَ قَالَ: قَالَ النَّبِيُّ صلى الله عليه وسلم: لاَ تَتَلاَعَنُوا بِلَعْنَةِ اللهِ، وَلاَ بِغَضَبِ اللهِ، وَلاَ بِالنَّارِ.
