Cursing a believer or calling accusing him of kufr (disbelief) is akin to murder

The Prophet ﷺ said, "Whoever swears by a religion other than Islam (i.e. if he swears by saying that he is a non-Muslim in case he is telling a lie), then he is as he says if his oath is false 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."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ حَلَفَ بِمِلَّةٍ غَيْرِ الإِسْلاَمِ كَاذِبًا فَهْوَ كَمَا قَالَ وَمَنْ قَتَلَ نَفْسَهُ بِشَىْءٍ عُذِّبَ بِهِ فِي نَارِ جَهَنَّمَ وَلَعْنُ الْمُؤْمِنِ كَقَتْلِهِ وَمَنْ رَمَى مُؤْمِنًا بِكُفْرٍ فَهْوَ كَقَتْلِهِ  

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."  

قَالَ النَّبِيُّ ﷺ مَنْ حَلَفَ بِغَيْرِ مِلَّةِ الإِسْلاَمِ فَهْوَ كَمَا قَالَ قَالَ وَمَنْ قَتَلَ نَفْسَهُ بِشَىْءٍ عُذِّبَ بِهِ فِي نَارِ جَهَنَّمَ وَلَعْنُ الْمُؤْمِنِ كَقَتْلِهِ وَمَنْ رَمَى مُؤْمِنًا بِكُفْرٍ فَهْوَ كَقَتْلِهِ  

None is obliged to give votive offering (of a thing) which is not in his possession and the cursing of a believer is tantamount to killing him, and he who killed himself with a thing in this world would be tormented with that (very thing) on the Day of Resurrection, and he who made a false claim to increase (his wealth), Allah would make no addition but that of paucity, and he who perjured would earn the wrath of God  

عَنِ النَّبِيِّ ﷺ قَالَ لَيْسَ عَلَى رَجُلٍ نَذْرٌ فِيمَا لاَ يَمْلِكُ وَلَعْنُ الْمُؤْمِنِ كَقَتْلِهِ وَمَنْ قَتَلَ نَفْسَهُ بِشَىْءٍ فِي الدُّنْيَا عُذِّبَ بِهِ يَوْمَ الْقِيَامَةِ وَمَنِ ادَّعَى دَعْوَى كَاذِبَةً لِيَتَكَثَّرَ بِهَا لَمْ يَزِدْهُ اللَّهُ إِلاَّ قِلَّةً وَمَنْ حَلَفَ عَلَى يَمِينِ صَبْرٍ فَاجِرَةٍ  

"Whoever swears by a religion other than Islam, telling a lie, will be as he said, and whoever kills himself with something, he will be punished with it in the Hereafter, and there is no vow concerning that which a man does not possess."  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ حَلَفَ بِمِلَّةٍ سِوَى مِلَّةِ الإِسْلاَمِ كَاذِبًا فَهُوَ كَمَا قَالَ وَمَنْ قَتَلَ نَفْسَهُ بِشَىْءٍ فِي الدُّنْيَا عُذِّبَ بِهِ يَوْمَ الْقِيَامَةِ وَلَيْسَ عَلَى رَجُلٍ نَذْرٌ فِيمَا لاَ يَمْلِكُ  

that the Prophet ﷺ said: "It is not for a slave (of Allah) to vow about something he does not possess, and cursing a believer is like killing him, and whoever accuses a believer of disbelief, then it is like he has killed him, and whoever kills himself with something, then Allah will punish him with whatever he killed himself with on the Day of Judgement."  

عَنِ النَّبِيِّ ﷺ قَالَ لَيْسَ عَلَى الْعَبْدِ نَذْرٌ فِيمَا لاَ يَمْلِكُ وَلاَعِنُ الْمُؤْمِنِ كَقَاتِلِهِ وَمَنْ قَذَفَ مُؤْمِنًا بِكُفْرٍ فَهُوَ كَقَاتِلِهِ وَمَنْ قَتَلَ نَفْسَهُ بِشَيْءٍ عَذَّبَهُ اللَّهُ بِمَا قَتَلَ بِهِ نَفْسَهُ يَوْمَ الْقِيَامَةِ وَفِي الْبَابِ عَنْ أَبِي ذَرٍّ وَابْنِ عُمَرَ  

[Machine] "The Prophet ﷺ said, 'Cursing a believer is like killing him, and whoever kills himself with something in this world will be punished with it in the hereafter. It is not permissible for a Muslim to make a vow about something he does not possess. And whoever accuses a believer of disbelief, it is as if he has killed him. And whoever takes an oath to a religion other than Islam falsely, he is as he said.'"  

أَنَّ النَّبِيَّ ﷺ قَالَ لَعْنُ الْمُؤْمِنِ كَقَتْلِهِ وَمَنْ قَتَلَ نَفْسَهُ بِشَيْءٍ فِي الدُّنْيَا عُذِّبَ بِهِ فِي الْآخِرَةِ وَلَيْسَ عَلَى رَجُلٍ مُسْلِمٍ نَذْرٌ فِيمَا لَا يَمْلِكُ وَمَنْ رَمَى مُؤْمِنًا بِكُفْرٍ فَهُوَ كَقَتْلِهِ وَمَنْ حَلَفَ بِمِلَّةٍ سِوَى الْإِسْلَامِ كَاذِبًا فَهُوَ كَمَا قَالَ  

That he took oath of allegiance to the Messenger of Allah ﷺ under the tree. The Messenger of Allah ﷺ said: If anyone swears by religion other than Islam falsely, he is like what has has said. If anyone kills himself with something, he will be punished with it on the Day of Resurrection. A vow over which a man has no control is not binding on him. (Using translation from Abū Dāʾūd 3257)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ حَلَفَ عَلَى يَمِينٍ بِمِلَّةٍ سِوَى الْإِسْلَامِ كَاذِبًا فَهُوَ كَمَا قَالَ وَمَنْ قَتَلَ نَفْسَهُ بِشَيْءٍ عُذِّبَ بِهِ يَوْمَ الْقِيَامَةِ وَلَيْسَ عَلَى رَجُلٍ نَذْرٌ فِيمَا لَا يَمْلِكُ

And whoever accuses a Muslim or claims disbelief, he will be as if he has killed him. And whoever curses him, he will be as if he has killed him. And whoever swears falsely on a religion other than Islam, he will be as he swore."

And whoever swears by a religion other than Islam falsely, then it is as if he has sworn falsely."

And whoever makes a false, deliberate oath on anything other than Islam, then he is as he said. And whoever kills himself with something, he will be punished with it in the Fire."
