Narrated Thabit bin Ad-Dahhak:
The Prophet ﷺ said, "Whoever swears by a religion other than Islam, is, as he says;
and whoever commits suicide with something, will be punished with the same thing in the (Hell) Fire;
and cursing a believer is like murdering him;
and whoever accuses a believer of disbelief, then it is as if he had killed him."
وَقَالَ عَمْرُو بْنُ عَاصِمٍ حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا إِسْحَاقُ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ أَبِي عَمْرَةَ، أَنَّ أَبَا هُرَيْرَةَ، حَدَّثَهُ أَنَّهُ، سَمِعَ النَّبِيَّ ﷺ يَقُولُ " إِنَّ ثَلاَثَةً فِي بَنِي إِسْرَائِيلَ أَرَادَ اللَّهُ أَنْ يَبْتَلِيَهُمْ، فَبَعَثَ مَلَكًا فَأَتَى الأَبْرَصَ فَقَالَ تَقَطَّعَتْ بِي الْحِبَالُ، فَلاَ بَلاَغَ لِي إِلاَّ بِاللَّهِ، ثُمَّ بِكَ ". فَذَكَرَ الْحَدِيثَ.
