The Prohibition of swearing to abandon a Good Deed

Allah commands, `You should not implement your vows in Allah's Name to refrain from pious acts and severing the relations with the relatives, if you swear to abandon such causes.' Allah said in another Ayah:

وَلاَ يَأْتَلِ أُوْلُواْ الْفَضْلِ مِنكُمْ وَالسَّعَةِ أَن يُؤْتُواْ أُوْلِى الْقُرْبَى وَالْمَسَـكِينَ وَالْمُهَـجِرِينَ فِى سَبِيلِ اللَّهِ وَلْيَعْفُواْ وَلْيَصْفَحُواْ أَلاَ تُحِبُّونَ أَن يَغْفِرَ اللَّهُ لَكُمْ

(And let not those among you who are blessed with graces and wealth swear not to give (any sort of help) to their kinsmen, Al-Masakin (the poor), and those who left their homes for Allah's cause. Let them pardon and forgive. Do you not love that Allah should forgive you) (24:22)

Continuity in a sinful vow is more sinful than breaking it by expiation. Allah's Messenger ﷺ said:

«وَاللهِ لَأَنْ يَلَجَّ أَحَدُكُمْ بِيَمِينِهِ فِي أَهْلِهِ آثَمُ لَهُ عِنْد اللهِ مِنْ أَنْ يُعْطِيَ كَفَّارَتَهُ الَّتِي افْتَرَضَ اللهُ عَلَيْه»

(By Allah! It is more sinful to Allah that one of you implements his vow regarding (severing the relations with) his relatives than (breaking his promise and) paying the Kaffarah that Allah has required in such cases.)

This is how Muslim reported this Hadith and also Imam Ahmad.

`Ali bin Abu Talhah reported that Ibn `Abbas said that what Allah said:

وَلاَ تَجْعَلُواْ اللَّهَ عُرْضَةً لاًّيْمَـنِكُمْ

(And make not Allah's (Name) an excuse in your oaths) means, "Do not vow to refrain from doing good works. (If you make such vow then) break it, pay the Kaffarah and do the good work." This was also said by Masruq, Ash-Sha`bi, Ibrahim An-Nakha`i, Mujahid, Tawus, Sa`id bin Jubayr, `Ata', `Ikrimah, Makhul, Az-Zuhri, Al-Hasan, Qatadah, Muqatil bin Hayyan, Ar-Rabi` bin Anas, Ad-Dahhak, `Ata' Al-Khurasani and As-Suddi.

Suporting this view, which is the majority view, is what is reported in the Two Sahihs that Abu Musa Al-Ash`ari narrated that Allah's Messenger ﷺ said: .

«إِنِّي وَاللهِ إِنْ شَاءَ اللهُ، لَا أَحْلِفُ عَلى يَمِينٍ فَأَرَى غَيْرَهَا خَيْرًا مِنْهَا إِلَّا أَتَيْتُ الَّذِي هُوَ خَيْرٌ وَتَحَلَّلْتُهَا»

(By Allah! Allah willing, I will not vow to do a thing and then see a better act, but I would do what is better and break my vow.) Muslim reported that Abu Hurayrah said that Allah's Messenger ﷺ said:

«مَنْ حَلَفَ عَلى يَمِينٍ فَرَأَى غَيْرَهَا خَيْرًا مِنْهَا فَلْيُكَفِّرْ عَنْ يَمِينِهِ، وَلْيَفْعَلِ الَّذِي هُوَ خَيْر»

(Whoever makes a vow and then finds what is better than his vow (should break his vow,) pay the Kaffarah and perform the better deed.)

The Laghw (Unintentional) Vows

Allah said:

لاَّ يُؤَاخِذُكُمُ اللَّهُ بِالَّلغْوِ فِى أَيْمَـنِكُمْ

(Allah will not call you to account for that which is unintentional in your oaths,)

This Ayah means, `Allah does not punish or hold you accountable for the Laghw (unintentional) vows that you make.' The Laghw vows are unintentional and are just like the habitual statements that the tongue repeats, without really intending them. For instance, it is reported in the Two Sahihs that Abu Hurayrah narrated that Allah's Messenger ﷺ said:

«مَنْ حَلَفَ فَقَالَ فِي حَلِفِهِ بِاللَّاتِ وَالْعُزَّى، فَلْيَقُلْ لَا إِلَهَ إِلَّا الله»

(Whoever swore and (unintentionally) mentioned Al-Lat and Al-`Uzza (two idols) in his vow, should then say, `There is no deity worthy of worship except Allah'.)

The Messenger said this statement to some new Muslims whose tongues were, before Islam, used to vowing by their idol Al-Lat. Therefore, the Prophet ordered them to intentionally recite the slogan of Ikhlas, just as they mentioned these words by mistake, so that it (the word of Ikhlas) may eradicate the word (of Shirk). This is why Allah said:

وَلَـكِن يُؤَاخِذُكُم بِمَا كَسَبَتْ قُلُوبُكُمْ

(...but He will call you to account for that which your hearts have earned.) and in another Ayah:

بِمَا عَقَّدتُّمُ الاٌّيْمَـنَ

(...for your deliberate oaths) (5:89)

Abu Dawud reported under Chapter: `The Laghw Vows' that `Ata' said that `A'ishah said that Allah's Messenger ﷺ said:

«اللَّغْوُ فِي الْيَمِينِ هُوَ كَلَامُ الرَّجُلِ فِي بَيْتِهِ: كَلَّا وَاللهِ، وَبَلَى وَالله»

(The Laghw in the vows includes what the man says in his house, such as, `No, by Allah,' and, `Yes, by Allah'.)

Ibn Abu Hatim reported that Ibn `Abbas said, "The Laghw vow includes vowing while angry."

He also reported that Ibn `Abbas said, "The Laghw vow includes vowing to prohibit what Allah has allowed, and this type does not require a Kaffarah (expiation)." Similar was said by Sa`id bin Jubayr.

In addition, Abu Dawud related under Chapter: `Vowing while Angry' that Sa`id bin Musayyib said that two Ansari brothers both received inheritance and one of them asked that the inheritance be divided. His brother said, "If you ask me about dividing the inheritance again, then all of what I have will be spent on the Ka`bah's door." `Umar said to him, "The Ka`bah does not need your money. So break your vow, pay the Kaffarah and come to terms with your brother. I heard Allah's Messenger ﷺ saying:

«لَا يَمِينَ عَلَيْكَ وَلَا نَذْرَ فِي مَعْصِيَةِ الرَّبِّ عَزَّ وَجَلَّ، وَفِي قَطِيعَةِ الرَّحِمِ، وَفِيمَا لَا تَمْلِك»

(Do not make a vow against yourself, nor to disobey the Lord, cut the relations of the womb or dispose of what you do not own.)"

Allah said:

وَلَـكِن يُؤَاخِذُكُم بِمَا كَسَبَتْ قُلُوبُكُمْ

(. ..but He will call you to account for that which your hearts have earned,)

Ibn `Abbas, Mujahid and several others said that this Ayah means swearing about a matter while knowing that he is lying. Mujahid and others said this Ayah is similar to what Allah said:

وَلَـكِن يُؤَاخِذُكُم بِمَا عَقَّدتُّمُ الاٌّيْمَـنَ

(...but He will punish you for your deliberate oaths.) (5:89) Allah said (2:225 above):

وَاللَّهُ غَفُورٌ حَلِيمٌ

(And Allah is Oft-Forgiving, Most-Forbearing.) meaning, He is Oft-Forgiving to His servants and Most Forbearing with them.
