The Light
فَإِن لَّمْ تَجِدُوا۟ فِيهَآ أَحَدًا فَلَا تَدْخُلُوهَا حَتَّىٰ يُؤْذَنَ لَكُمْ ۖ وَإِن قِيلَ لَكُمُ ٱرْجِعُوا۟ فَٱرْجِعُوا۟ ۖ هُوَ أَزْكَىٰ لَكُمْ ۚ وَٱللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌ
And if you do not find anyone therein, do not enter them until permission has been given you. And if it is said to you, "Go back," then go back; it is purer for you. And Allah is Knowing of what you do.

ٱلْخَبِيثَـٰتُ لِلْخَبِيثِينَ وَٱلْخَبِيثُونَ لِلْخَبِيثَـٰتِ ۖ وَٱلطَّيِّبَـٰتُ لِلطَّيِّبِينَ وَٱلطَّيِّبُونَ لِلطَّيِّبَـٰتِ ۚ أُو۟لَـٰٓئِكَ مُبَرَّءُونَ مِمَّا يَقُولُونَ ۖ لَهُم مَّغْفِرَةٌ وَرِزْقٌ كَرِيمٌ
Evil words are for evil men, and evil men are [subjected] to evil words. And good words are for good men, and good men are [an object] of good words. Those [good people] are declared innocent of what the slanderers say. For them is forgiveness and noble provision.
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَدْخُلُوا۟ بُيُوتًا غَيْرَ بُيُوتِكُمْ حَتَّىٰ تَسْتَأْنِسُوا۟ وَتُسَلِّمُوا۟ عَلَىٰٓ أَهْلِهَا ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ لَعَلَّكُمْ تَذَكَّرُونَ
O you who have believed, do not enter houses other than your own houses until you ascertain welcome and greet their inhabitants. That is best for you; perhaps you will be reminded.
لَّيْسَ عَلَيْكُمْ جُنَاحٌ أَن تَدْخُلُوا۟ بُيُوتًا غَيْرَ مَسْكُونَةٍ فِيهَا مَتَـٰعٌ لَّكُمْ ۚ وَٱللَّهُ يَعْلَمُ مَا تُبْدُونَ وَمَا تَكْتُمُونَ
There is no blame upon you for entering houses not inhabited in which there is convenience for you. And Allah knows what you reveal and what you conceal.
قُل لِّلْمُؤْمِنِينَ يَغُضُّوا۟ مِنْ أَبْصَـٰرِهِمْ وَيَحْفَظُوا۟ فُرُوجَهُمْ ۚ ذَٰلِكَ أَزْكَىٰ لَهُمْ ۗ إِنَّ ٱللَّهَ خَبِيرٌۢ بِمَا يَصْنَعُونَ
Tell the believing men to reduce [some] of their vision and guard their private parts. That is purer for them. Indeed, Allah is Acquainted with what they do.
