3:35
إِذْ قَالَتِ ٱمْرَأَتُ عِمْرَٰنَ رَبِّ إِنِّ ى نَذَرْ تُ لَ كَ مَا فِى بَطْنِ ى مُحَرَّرًا فَ تَقَبَّلْ مِنِّ ىٓ إِنَّ كَ أَنتَ ٱل سَّمِيعُ ٱلْ عَلِيمُ
[Mention, O Muhammad], when the wife of 'Imran said, "My Lord, indeed I have pledged to You what is in my womb, consecrated [for Your service], so accept this from me. Indeed, You are the Hearing, the Knowing."
4:92
وَ مَا كَانَ لِ مُؤْمِنٍ أَن يَقْتُلَ مُؤْمِنًا إِلَّا خَطَـًٔا وَ مَن قَتَلَ مُؤْمِنًا خَطَـًٔا فَ تَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ وَ دِيَةٌ مُّسَلَّمَةٌ إِلَىٰٓ أَهْلِ هِۦٓ إِلَّآ أَن يَصَّدَّقُ وا۟ فَ إِن كَانَ مِن قَوْمٍ عَدُوٍّ لَّ كُمْ وَ هُوَ مُؤْمِنٌ فَ تَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ وَ إِن كَانَ مِن قَوْمٍۭ بَيْنَ كُمْ وَ بَيْنَ هُم مِّيثَٰقٌ فَ دِيَةٌ مُّسَلَّمَةٌ إِلَىٰٓ أَهْلِ هِۦ وَ تَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ فَ مَن لَّمْ يَجِدْ فَ صِيَامُ شَهْرَيْنِ مُتَتَابِعَيْنِ تَوْبَةً مِّنَ ٱللَّهِ وَ كَانَ ٱللَّهُ عَلِيمًا حَكِيمًا
And never is it for a believer to kill a believer except by mistake. And whoever kills a believer by mistake - then the freeing of a believing slave and a compensation payment presented to the deceased's family [is required] unless they give [up their right as] charity. But if the deceased was from a people at war with you and he was a believer - then [only] the freeing of a believing slave; and if he was from a people with whom you have a treaty - then a compensation payment presented to his family and the freeing of a believing slave. And whoever does not find [one or cannot afford to buy one] - then [instead], a fast for two months consecutively, [seeking] acceptance of repentance from Allah. And Allah is ever Knowing and Wise.
58:3
وَ ٱلَّذِينَ يُظَٰهِرُ ونَ مِن نِّسَآئِ هِمْ ثُمَّ يَعُودُ ونَ لِ مَا قَالُ وا۟ فَ تَحْرِيرُ رَقَبَةٍ مِّن قَبْلِ أَن يَتَمَآسَّ ا ذَٰلِكُمْ تُوعَظُ ونَ بِ هِۦ وَ ٱللَّهُ بِ مَا تَعْمَلُ ونَ خَبِيرٌ
And those who pronounce thihar from their wives and then [wish to] go back on what they said - then [there must be] the freeing of a slave before they touch one another. That is what you are admonished thereby; and Allah is Acquainted with what you do.
5:89
لَا يُؤَاخِذُ كُمُ ٱللَّهُ بِ ٱل لَّغْوِ فِىٓ أَيْمَٰنِ كُمْ وَ لَٰكِن يُؤَاخِذُ كُم بِ مَا عَقَّد تُّمُ ٱلْ أَيْمَٰنَ فَ كَفَّٰرَتُ هُۥٓ إِطْعَامُ عَشَرَةِ مَسَٰكِينَ مِنْ أَوْسَطِ مَا تُطْعِمُ ونَ أَهْلِي كُمْ أَوْ كِسْوَتُ هُمْ أَوْ تَحْرِيرُ رَقَبَةٍ فَ مَن لَّمْ يَجِدْ فَ صِيَامُ ثَلَٰثَةِ أَيَّامٍ ذَٰلِكَ كَفَّٰرَةُ أَيْمَٰنِ كُمْ إِذَا حَلَفْ تُمْ وَ ٱحْفَظُ وٓا۟ أَيْمَٰنَ كُمْ كَ ذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَ كُمْ ءَايَٰتِ هِۦ لَعَلَّ كُمْ تَشْكُرُ ونَ
Allah will not impose blame upon you for what is meaningless in your oaths, but He will impose blame upon you for [breaking] what you intended of oaths. So its expiation is the feeding of ten needy people from the average of that which you feed your [own] families or clothing them or the freeing of a slave. But whoever cannot find [or afford it] - then a fast of three days [is required]. That is the expiation for oaths when you have sworn. But guard your oaths. Thus does Allah make clear to you His verses that you may be grateful.
