The Prophet ﷺ said: If anyone says when swearing an oath: "If Allah wills," he makes an exception. (Using translation from Abū Dāʾūd 3261)   

النَّبِيَّ ﷺ قَالَ مَنْ حَلَفَ عَلَى يَمِينٍ فَقَالَ إِنْ شَاءَ اللهُ فَقَدِ اسْتَثْنَى  

[Machine] The Messenger of Allah ﷺ said, "Whoever takes an oath and says 'Insha'Allah' (if Allah wills), then he will have two rewards: one for fulfilling the oath and another for the expression of 'Insha'Allah'. This is narrated from the first of the benefits of Abu 'Amr bin Hamdan, Ayoub bin Musa, and likewise it is narrated from Ibn Wahb, from Sufyan, from Ayoub bin Musa. Indeed, this hadith is only known as marfu' (attributed to the Prophet) from the hadith of Ayoub al-Sakhityani."  

قَالَ رَسُولُ اللهِ ﷺ مَنْ حَلَفَ فَقَالَ إِنْ شَاءَ اللهُ فَلَهُ ثُنْيَا كَذَا وَجَدْتُهُ وَهُوَ فِي الْأَوَّلِ مِنْ فَوَائِدِ أَبِي عَمْرِو بْنِ حَمْدَانَ أَيُّوبَ بْنِ مُوسَى وَكَذَلِكَ رُوِيَ عَنِ ابْنِ وَهْبٍ عَنْ سُفْيَانَ عَنْ أَيُّوبَ بْنِ مُوسَى وَإِنَّمَا يُعْرَفُ هَذَا الْحَدِيثُ مَرْفُوعًا مِنْ حَدِيثِ أَيُّوبَ السَّخْتِيَانِيِّ  

"Whoever swears an oath and says, 'If Allah wills,' then he has the choice: If he wishes, he may go ahead, and if he wishes he may not." (Using translation from Nasāʾī 3830)   

النَّبِيَّ ﷺ قَالَ مَنْ حَلَفَ عَلَى يَمِينٍ فَقَالَ إِنْ شَاءَ اللهُ فَهُوَ بِالْخِيَارِ إِنْ شَاءَ فَلْيَمْضِ وَإِنْ شَاءَ فَلْيَتْرُكْ  

[Machine] Whoever swears an oath and adds an exception, he has the choice to fulfill it if he wants to continue on his oath, or he has the choice to retract it without any blame. Abu Bakr ibn al-Harith al-Faqih informed us, Abu Muhammad ibn Hayyan al-Asbahani narrated to us, Abdan narrated to us, Abu Bakr ibn Abi Shaybah narrated to us, Ibn Ulayyah mentioned it in a similar way except that he said, "I only know this from the Prophet's ﷺ mention of Ayyub." He said regarding him, "The doubt was from Ayyub." And he said at the end, "He retracted it without falsehood." Abu Bakr ibn al-Harith al-Faqih informed us, Abu Muhammad ibn Hayyan narrated to us, Abdan narrated to us, Abu Bakr ibn Khalad narrated, Hammad ibn Zayd said, Ayyub used to transmit this hadith, then he stopped. The sheikh said, "Perhaps he stopped transmitting it due to doubt in its transmission." And he is Ayyub ibn Abi Tamimah al-Sakhtiyani. And it has also been narrated from Musa ibn Uqbah, Abdullah ibn Umar, Hassan ibn Atiya, and Kathir ibn Farqad, from Nafi', from Ibn Umar, from the Prophet ﷺ. And its transmission is hardly considered authentic except from the perspective of Ayyub al-Sakhtiyani. And Ayyub also had doubt in it. And the narration of the majority is correct from various perspectives according to Nafi', from Ibn Umar, from his statement not being raised. And Allah knows best.  

ﷺ مَنْ حَلَفَ فَاسْتَثْنَى فَهُوَ بِالْخِيَارِ إِنْ شَاءَ أَنْ يَمْضِيَ عَلَى يَمِينِهِ مَضَى وَإِنْ شَاءَ أَنْ يَرْجِعَ رَجَعَ غَيْرَ حَرِجٍ 19918 وَأَخْبَرَنَا أَبُو بَكْرِ بْنُ الْحَارِثِ الْفَقِيهُ أنبأ أَبُو مُحَمَّدِ بْنُ حَيَّانَ الْأَصْبَهَانِيُّ ثنا عَبْدَانُ ثنا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ثنا ابْنُ عُلَيَّةَ فَذَكَرَهُ بِنَحْوِهِ إِلَّا أَنَّهُ قَالَ لَا أَعْلَمُ إِلَّا عَنِ النَّبِيِّ ﷺ الشَّكُّ مِنْ أَيُّوبَ وَقَالَ فِي آخِرِهِ رَجَعَ غَيْرَ حَنِثٍ 19919 أَخْبَرَنَا أَبُو بَكْرِ بْنُ الْحَارِثِ الْفَقِيهُ ثنا أَبُو مُحَمَّدِ بْنُ حَيَّانَ ثنا عَبْدَانُ ثنا أَبُو بَكْرِ بْنُ خَلَّادٍ قَالَ قَالَ حَمَّادُ بْنُ زَيْدٍ كَانَ أَيُّوبُ يَرْفَعُ هَذَا الْحَدِيثَ ثُمَّ تَرَكَهُ قَالَ الشَّيْخُ لَعَلَّهُ إِنَّمَا تَرَكَهُ لِشَكٍّ اعْتَرَاهُ فِي رَفْعِهِ وَهُوَ أَيُّوبُ بْنُ أَبِي تَمِيمَةَ السَّخْتِيَانِيُّ وَقَدْ رُوِيَ ذَلِكَ أَيْضًا عَنْ مُوسَى بْنِ عُقْبَةَ وَعَبْدِ اللهِ بْنِ عُمَرَ وَحَسَّانَ بْنِ عَطِيَّةَ وَكَثِيرِ بْنِ فَرْقَدٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ ؓ عَنِ النَّبِيِّ ﷺ وَلَا يَكَادُ يَصِحُّ رَفْعُهُ إِلَّا مِنْ جِهَةِ أَيُّوبَ السَّخْتِيَانِيِّ وَأَيُّوبُ يَشُكُّ فِيهِ أَيْضًا وَرِوَايَةُ الْجَمَاعَةِ مِنْ أَوْجُهٍ صَحِيحَةٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ ؓ مِنْ قَوْلِهِ غَيْرَ مَرْفُوعٍ وَاللهُ أَعْلَمُ  

[Machine] If Allah wills, and he did not do what he swore upon, then he did not break his oath.  

إِنْ شَاءَ اللهُ فَلَمْ يَفْعَلِ الَّذِي حَلَفَ عَلَيْهِ لَمْ يَحْنَثْ  

The Prophet ﷺ said: If anyone says when swearing an oath: "If Allah wills," he makes an exception. (Using translation from Abū Dāʾūd 3261)   

إِنْ شَاءَ اللهُ فَقَدِ اسْتَثْنَى  

[Machine] Regarding Ata and Tawus and Mujahid, an exception is made in divorce, emancipation, and in everything permissible. And what was narrated about Muadh, elevated and mentioned in the book of divorce.  

عَنْ عَطَاءٍ وَطَاوُسٍ وَمُجَاهِدٍ الِاسْتِثْنَاءُ فِي الطَّلَاقِ وَفِي الْعِتَاقِ وَفِي كُلِّ شَيْءٍ جَائِزٌ وَالَّذِي رُوِيَ فِيهِ عَنْ مُعَاذٍ مَرْفُوعًا مَذْكُورٌ فِي كِتَابِ الطَّلَاقِ  

[Machine] The Messenger of Allah ﷺ said, "O Mu'adh bin Jabal, when a man says to his wife, 'You are divorced if Allah wills,' then she is not divorced. And when he says to his slave, 'You are free if Allah wills,' then he is free." Humaid bin Malik narrated this hadith, but his credibility is unknown, and there is disagreement about the chain of narrators. It is said that this narration is from Mak'hool from Malik bin Yu'khmur from Mu'adh, and it is also said that it is from Mak'hool from Mu'adh, and this chain is broken.  

قَالَ رَسُولُ اللهِ ﷺ يَا مُعَاذُ بْنَ جَبَلٍ إِذَا قَالَ الرَّجُلُ لِامْرَأَتِهِ أَنْتِ طَالِقٌ إِنْ شَاءَ اللهُ لَمْ تُطَلَّقْ وَإِذَا قَالَ لِعَبْدِهِ أَنْتَ حُرٌّ إِنْ شَاءَ اللهُ فَإِنَّهُ حُرٌّ تَفَرَّدَ بِهِ حُمَيْدُ بْنُ مَالِكٍ وَهُوَ مَجْهُولٌ وَاخْتُلِفَ عَلَيْهِ فِي إِسْنَادِهِ فَقِيلَ هَكَذَا وَقِيلَ عَنْهُ عَنْ مَكْحُولٍ عَنْ مَالِكِ بْنِ يُخَامِرَ عَنْ مُعَاذٍ وَقِيلَ عَنْهُ عَنْ مَكْحُولٍ عَنْ مُعَاذٍ وَهُوَ مُنْقَطِعٌ
