Al-Kāfi - Volume 7 > The Meaningless Matters
Hadith #1

1- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ بْنِ صَدَقَةَ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ سَمِعْتُهُ يَقُولُ فِي قَوْلِ اللهِ عَزَّ وَجَلَّ لا يُؤاخِذُكُمُ اللهُ بِاللَّغْوِ فِي أَيْمانِكُمْ قَالَ اللَّغْوُ قَوْلُ الرَّجُلِ لا وَاللهِ وَبَلَى وَاللهِ وَلا يَعْقِدُ عَلَى شَيْ‏ءٍ.

1. Ali ibn Ibrahim has narrated from Harun ibn Muslim from Mas’adah ibn Sadaqah who has narrated the following: “I once heard abu ‘Abd Allah, ‘Alayhi al-Salam, saying, about the meaning of the words of Allah, ‘. . . Allah will not hold you responsible for your meaningless oaths.’ (2:225) Al-Laghw, (meaningless) is a reference to a man’s saying, ‘La wa Allah, (No, by Allah) Bala waAllah-i, (yes, by Allah)’ and it does not make anything binding.”
