Quran 24:61

لَّيۡسَ عَلَى ٱلۡأَعۡمَىٰ حَرَجٌ۬ وَلَا عَلَى ٱلۡأَعۡرَجِ حَرَجٌ۬ وَلَا عَلَى ٱلۡمَرِيضِ حَرَجٌ۬ وَلَا عَلَىٰٓ أَنفُسِڪُمۡ أَن تَأۡكُلُواْ مِنۢ بُيُوتِڪُمۡ أَوۡ بُيُوتِ ءَابَآٮِٕڪُمۡ أَوۡ بُيُوتِ أُمَّهَـٰتِكُمۡ أَوۡ بُيُوتِ إِخۡوَٲنِڪُمۡ أَوۡ بُيُوتِ أَخَوَٲتِڪُمۡ أَوۡ بُيُوتِ أَعۡمَـٰمِڪُمۡ أَوۡ بُيُوتِ عَمَّـٰتِڪُمۡ أَوۡ بُيُوتِ أَخۡوَٲلِكُمۡ أَوۡ بُيُوتِ خَـٰلَـٰتِڪُمۡ أَوۡ مَا مَلَڪۡتُم مَّفَاتِحَهُ ۥۤ أَوۡ صَدِيقِڪُمۡ‌ۚ لَيۡسَ عَلَيۡڪُمۡ جُنَاحٌ أَن تَأۡڪُلُواْ جَمِيعًا أَوۡ أَشۡتَاتً۬ا‌ۚ فَإِذَا دَخَلۡتُم بُيُوتً۬ا فَسَلِّمُواْ عَلَىٰٓ أَنفُسِكُمۡ تَحِيَّةً۬ مِّنۡ عِندِ ٱللهِ مُبَـٰرَڪَةً۬ طَيِّبَةً۬‌ۚ ڪَذَٲلِكَ يُبَيِّنُ ٱللَّهُ لَڪُمُ ٱلۡأَيَـٰتِ لَعَلَّڪُمۡ تَعۡقِلُونَ ٦١

The blind is not to be blamed, the crippled is not to be blamed, nor is the handicapped to be blamed, just as you are not to be blamed for eating at your homes, or the homes of your fathers, or the homes of your mothers, or the homes of your brothers, or the homes of your sisters, or the homes of your fathers’ brothers, or the homes of your fathers’ sisters, or the homes of your mothers’ brothers, or the homes of your mothers’ sisters, or the homes that belong to you and you possess their keys, or the homes of your friends. You commit nothing wrong by eating together or as individuals. When you enter any home, you shall greet each other a greeting from ALLAH that is blessed and good. ALLAH thus explains the revelations for you, that you may understand.
