يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَدۡخُلُواْ بُيُوتًا غَيۡرَ بُيُوتِكُمۡ حَتَّىٰ تَسۡتَأۡنِسُواْ وَتُسَلِّمُواْ عَلَىٰٓ أَهۡلِهَا ۚ ذَٰلِكُمۡ خَيۡرٌ لَّكُمۡ لَعَلَّكُمۡ تَذَكَّرُونَ
O ye who believe! enter not houses other than your own, until ye have asked permission and saluted those in them: that is best for you, in order that ye may heed (what is seemly).<br/>
O you who believe, do not enter houses other than your houses until you have [first] asked permission and greeted their occupants. So a person must say, 'Peace be upon you, may I enter?', as is stated in one hadeeth. That is better for you, than entering without permission, that perhaps you might remember (tadhakkaroona: the second taa' [of tatadhakkaroona] has been assimilated with the dhaal) the superiority of such [conduct] and so follow it.
