33:53
يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَدْخُلُوا بُيُوتَ النَّبِيِّ إِلَّا أَن يُؤْذَنَ لَكُمْ إِلَى طَعَامٍ غَيْرَ نَاظِرِينَ إِنَاهُ وَلَكِنْ إِذَا دُعِيتُمْ فَادْخُلُوا فَإِذَا طَعِمْتُمْ فَانتَشِرُوا وَلَا مُسْتَأْنِسِينَ لِحَدِيثٍ إِنَّ ذَلِكُمْ كَانَ يُؤْذِي النَّبِيَّ فَيَسْتَحْيِي مِنكُمْ وَاللَّهُ لَا يَسْتَحْيِي مِنَ الْحَقِّ وَإِذَا سَأَلْتُمُوهُنَّ مَتَاعاً فَاسْأَلُوهُنَّ مِن وَرَاء حِجَابٍ ذَلِكُمْ أَطْهَرُ لِقُلُوبِكُمْ وَقُلُوبِهِنَّ وَمَا كَانَ لَكُمْ أَن تُؤْذُوا رَسُولَ اللَّهِ وَلَا أَن تَنكِحُوا أَزْوَاجَهُ مِن بَعْدِهِ أَبَداً إِنَّ ذَلِكُمْ كَانَ عِندَ اللَّهِ عَظِيماً
O ye who believe! Enter not the Prophet's houses,- until leave is given you,- for a meal, (and then) not (so early as) to wait for its preparation: but when ye are invited, enter; and when ye have taken your meal, disperse, without seeking familiar talk. Such (behaviour) annoys the Prophet: he is ashamed to dismiss you, but Allah is not ashamed (to tell you) the truth. And when ye ask (his ladies) for anything ye want, ask them from before a screen: that makes for greater purity for your hearts and for theirs. Nor is it right for you that ye should annoy Allah's Messenger, or that ye should marry his widows after him at any time. Truly such a thing is in Allah's sight an enormity.
41:5
وَقَالُوا قُلُوبُنَا فِي أَكِنَّةٍ مِّمَّا تَدْعُونَا إِلَيْهِ وَفِي آذَانِنَا وَقْرٌ وَمِن بَيْنِنَا وَبَيْنِكَ حِجَابٌ فَاعْمَلْ إِنَّنَا عَامِلُونَ
They say: "Our hearts are under veils, (concealed) from that to which thou dost invite us, and in our ears in a deafness, and between us and thee is a screen: so do thou (what thou wilt); for us, we shall do (what we will!)"
