PERMISSION يَأَيُّهَا الَّذِينَ ءَامَنُوا لَا تَدْخُلُوا بُيُوتًا غَيْرَ بُيُوتِكُمْ حَتَّى تَسْتَأْنِسُوا وَتُسَلِّمُوا عَلَى أَهْلِهَا ذَلِكُمْ خَيْرٌ لَكُمْ لَعَلَّكُمْ تَذَكَّرُونَ . فَإِن لَّمْ تَجِدُوا فِيهَا أَحَدًا فَلَا نَدْخُلُوهَا حَتَّى يُؤْذَنَ لَكُروان قِيلَ لَكُمُ ارْجِعُوا فَارْجِعُوا هُوَ أَزْكَى لَكُمْ وَاللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌ لَّيْسَ عَلَيْكُمْ جُنَاحٌ أَن تَدْخُلُوا بُيُوتًا غَيْرَ مَسْكُونَةٍ فِيهَا مَتَعُ لَكُمْ وَاللَّهُ يَعْلَمُ مَا تُبْدُونَ وَمَا تَكْتُمُونَ. Allah says:. O believers do not enter any house other than your own without first taking permission from the occupants and greeting them. It is better for you that you remain well advised. . If you find no one therein, do not enter them until you are authorised to do so and in case the permission is not granted, then return without taking offence. That is better for you (meaning that is better for the purity and health of your social behaviour). Allah knows well what you do. . It is no sin on your part to enter houses where no body lives and wherein are your goods. Allah knows what you reveal and what you conceal. (24:28-30)
