The Prophet ﷺ ordered us to help others to fulfill the oaths.  

عَنِ النَّبِيِّ ﷺ وَحَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا غُنْدَرٌ حَدَّثَنَا شُعْبَةُ عَنْ أَشْعَثَ عَنْ مُعَاوِيَةَ بْنِ سُوَيْدِ بْنِ مُقَرِّنٍ عَنِ الْبَرَاءِ ؓ قَالَ أَمَرَنَا النَّبِيُّ ﷺ بِإِبْرَارِ الْمُقْسِمِ  

Once a daughter of Messenger of Allah ﷺ sent a message to Messenger of Allah ﷺ while Usama, Saʿd, and my father or Ubai were (sitting there) with him. She said, (in the message); My child is going to die; please come to us." Messenger of Allah ﷺ returned the messenger and told him to convey his greetings to her, and say, "Whatever Allah takes, is for Him and whatever He gives is for Him, and everything with Him has a limited fixed term (in this world): so she should be patient and hope for Allah's reward." Then she again sent for him swearing that he should come; so The Prophet ﷺ got up, and so did we. When he sat there (at the house of his daughter), the child was brought to him, and he took him into his lap while the child's breath was disturbed in his chest. The eyes of Messenger of Allah ﷺ started shedding tears. Saʿd said, "What is this, O Messenger of Allah ﷺ?" The Prophet ﷺ said, "This is the mercy which Allah has lodged in the hearts of whoever He wants of His slaves, and verily Allah is merciful only to those of His slaves who are merciful (to others).'  

أَنَّ ابْنَةً لِرَسُولِ اللَّهِ ﷺ أَرْسَلَتْ إِلَيْهِ وَمَعَ رَسُولِ اللَّهِ ﷺ أُسَامَةُ بْنُ زَيْدٍ وَسَعْدٌ وَأُبَىٌّ أَنَّ ابْنِي قَدِ احْتُضِرَ فَاشْهَدْنَا فَأَرْسَلَ يَقْرَأُ السَّلاَمَ وَيَقُولُ إِنَّ لِلَّهِ مَا أَخَذَ وَمَا أَعْطَى وَكُلُّ شَىْءٍ عِنْدَهُ مُسَمًّى فَلْتَصْبِرْ وَتَحْتَسِبْ فَأَرْسَلَتْ إِلَيْهِ تُقْسِمُ عَلَيْهِ فَقَامَ وَقُمْنَا مَعَهُ فَلَمَّا قَعَدَ رُفِعَ إِلَيْهِ فَأَقْعَدَهُ فِي حَجْرِهِ وَنَفْسُ الصَّبِيِّ تَقَعْقَعُ فَفَاضَتْ عَيْنَا رَسُولِ اللَّهِ ﷺ فَقَالَ سَعْدٌ مَا هَذَا يَا رَسُولَ اللَّهِ قَالَ هَذَا رَحْمَةٌ يَضَعُهَا اللَّهُ فِي قُلُوبِ مَنْ يَشَاءُ مِنْ عِبَادِهِ وَإِنَّمَا يَرْحَمُ اللَّهُ مِنْ عِبَادِهِ الرُّحَمَاءَ  

Messenger of Allah ﷺ said, "Any Muslim who has lost three of his children will not be touched by the Fire except that which will render Allah's oath fulfilled."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَمُوتُ لأَحَدٍ مِنَ الْمُسْلِمِينَ ثَلاَثَةٌ مِنَ الْوَلَدِ تَمَسُّهُ النَّارُ إِلاَّ تَحِلَّةَ الْقَسَمِ  

I heard the Prophet ﷺ saying, "Shall I tell you of the people of Paradise? They comprise every poor humble person, and if he swears by Allah to do something, Allah will fulfill it; while the people of the fire comprise every violent, cruel arrogant person."  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ أَلاَ أَدُلُّكُمْ عَلَى أَهْلِ الْجَنَّةِ كُلُّ ضَعِيفٍ مُتَضَعَّفٍ لَوْ أَقْسَمَ عَلَى اللَّهِ لأَبَرَّهُ وَأَهْلِ النَّارِ كُلُّ جَوَّاظٍ عُتُلٍّ مُسْتَكْبِرٍ
