Sura al-Nūr 24:6

وَٱلَّذِينَ يَرْمُونَ أَزْوَٰجَهُمْ وَلَمْ يَكُن لَّهُمْ شُهَدَآءُ إِلَّآ أَنفُسُهُمْ فَشَهَٰدَةُ أَحَدِهِمْ أَرْبَعُ شَهَٰدَٰتٍۭ بِٱللَّـهِ إِنَّهُۥ لَمِنَ ٱلصَّٰدِقِينَ

wa-lladhīna yarmūna azwājahum wa-lam yakun lahum shuhadāʾu illā anfusuhum fa-shahādatu aḥadihim arbaʿu shahādātin billāhi innahu la-mina l-ṣādiqīna

And for those who launch a charge against their spouses, and have (in support) no evidence but their own,- their solitary evidence (can be received) if they bear witness four times (with an oath) by Allah that they are solemnly telling the truth;

Sura al-Nūr 24:9

وَٱلْخَٰمِسَةَ أَنَّ غَضَبَ ٱللَّـهِ عَلَيْهَآ إِن كَانَ مِنَ ٱلصَّٰدِقِينَ

wa-l-khāmisata annā ghaḍaba allāhi ʿalayhā in kāna mina l-ṣādiqīna

And the fifth (oath) should be that she solemnly invokes the wrath of Allah on herself if (her accuser) is telling the truth.

Sura al-Nūr 24:61

لَّيْسَ عَلَى ٱلْأَعْمَىٰ حَرَجٌ وَلَا عَلَى ٱلْأَعْرَجِ حَرَجٌ وَلَا عَلَى ٱلْمَرِيضِ حَرَجٌ وَلَا عَلَىٰٓ أَنفُسِكُمْ أَن تَأْكُلُوا۟ مِنۢ بُيُوتِكُمْ أَوْ بُيُوتِ ءَابَآئِكُمْ أَوْ بُيُوتِ أُمَّهَٰتِكُمْ أَوْ بُيُوتِ إِخْوَٰنِكُمْ أَوْ بُيُوتِ أَخَوَٰتِكُمْ أَوْ بُيُوتِ أَعْمَٰمِكُمْ أَوْ بُيُوتِ عَمَّٰتِكُمْ أَوْ بُيُوتِ أَخْوَٰلِكُمْ أَوْ بُيُوتِ خَٰلَٰتِكُمْ أَوْ مَا مَلَكْتُم مَّفَاتِحَهُۥٓ أَوْ صَدِيقِكُمْ لَيْسَ عَلَيْكُمْ جُنَاحٌ أَن تَأْكُلُوا۟ جَمِيعًا أَوْ أَشْتَاتًا فَإِذَا دَخَلْتُم بُيُوتًا فَسَلِّمُوا۟ عَلَىٰٓ أَنفُسِكُمْ تَحِيَّةً مِّنْ عِندِ ٱللَّـهِ مُبَٰرَكَةً طَيِّبَةً كَذَٰلِكَ يُبَيِّنُ ٱللَّـهُ لَكُمُ ٱلْأَيَٰتِ لَعَلَّكُمْ تَعْقِلُونَ

It is no fault in the blind nor in one born lame, nor in one afflicted with illness, nor in yourselves, that ye should eat in your own houses, or those of your fathers, or your mothers, or your brothers, or your sisters, or your father's brothers or your father's sisters, or your mohter's brothers, or your mother's sisters, or in houses of which the keys are in your possession, or in the house of a sincere friend of yours: there is no blame on you, whether ye eat in company or separately. But if ye enter houses, salute each other - a greeting of blessing and purity as from Allah. Thus does Allah make clear the signs to you: that ye may understand.
