Vain talk (Laghw al-Qawl) in the Holy Quran

﴿لَّا يُؤَاخِذُكُمُ ٱللَّهُ بِٱللَّغۡوِ فِيٓ أَيۡمَٰنِكُمۡ وَلَٰكِن يُؤَاخِذُكُم بِمَا كَسَبَتۡ قُلُوبُكُمۡۗ وَٱللَّهُ غَفُورٌ حَلِيمٞ ﴾ [Al-Baqarah: 225]

(225) Allah does not impose blame upon you for what is unintentional in your oaths, but He imposes blame upon you for what your hearts have earned. And Allah is Forgiving and Forbearing.

Surah: Al-Baqarah - Verse: 225 - Juz: 2 - Page: 36

﴿لَا يُؤَاخِذُكُمُ ٱللَّهُ بِٱللَّغۡوِ فِيٓ أَيۡمَٰنِكُمۡ وَلَٰكِن يُؤَاخِذُكُم بِمَا عَقَّدتُّمُ ٱلۡأَيۡمَٰنَۖ فَكَفَّٰرَتُهُۥٓ إِطۡعَامُ عَشَرَةِ مَسَٰكِينَ مِنۡ أَوۡسَطِ مَا تُطۡعِمُونَ أَهۡلِيكُمۡ أَوۡ كِسۡوَتُهُمۡ أَوۡ تَحۡرِيرُ رَقَبَةٖۖ فَمَن لَّمۡ يَجِدۡ فَصِيَامُ ثَلَٰثَةِ أَيَّامٖۚ ذَٰلِكَ كَفَّٰرَةُ أَيۡمَٰنِكُمۡ إِذَا حَلَفۡتُمۡۚ وَٱحۡفَظُوٓاْ أَيۡمَٰنَكُمۡۚ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمۡ ءَايَٰتِهِۦ لَعَلَّكُمۡ تَشۡكُرُونَ ﴾ [Al-Mā’idah: 89]

(89) 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.

Surah: Al-Mā’idah - Verse: 89 - Juz: 7 - Page: 122

﴿ قَدۡ أَفۡلَحَ ٱلۡمُؤۡمِنُونَ * ٱلَّذِينَ هُمۡ فِي صَلَاتِهِمۡ خَٰشِعُونَ * وَٱلَّذِينَ هُمۡ عَنِ ٱللَّغۡوِ مُعۡرِضُونَ ﴾ [Al-Mu’minūn: 1-3]

(1) Certainly will the believers have succeeded:

(2) They who are during their prayer humbly submissive

(3) And they who turn away from ill speech

Surah: Al-Mu’minūn - Verse: 1-2-3 - Juz: 18 - Page: 342

﴿وَٱلَّذِينَ لَا يَشۡهَدُونَ ٱلزُّورَ وَإِذَا مَرُّواْ بِٱللَّغۡوِ مَرُّواْ كِرَامٗا ﴾ [Al-Furqān: 72]

(72) And [they are] those who do not testify to falsehood, and when they pass near ill speech, they pass by with dignity.

Surah: Al-Furqān - Verse: 72 - Juz: 19 - Page: 366

﴿وَإِذَا سَمِعُواْ ٱللَّغۡوَ أَعۡرَضُواْ عَنۡهُ وَقَالُواْ لَنَآ أَعۡمَٰلُنَا وَلَكُمۡ أَعۡمَٰلُكُمۡ سَلَٰمٌ عَلَيۡكُمۡ لَا نَبۡتَغِي ٱلۡجَٰهِلِينَ ﴾ [Al-Qaṣaṣ: 55]

(55) And when they hear ill speech, they turn away from it and say, "For us are our deeds, and for you are your deeds. Peace will be upon you; we seek not the ignorant."

Surah: Al-Qaṣaṣ - Verse: 55 - Juz: 20 - Page: 392
