﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَدْخُلُوا۟ بُيُوتًا غَيْرَ بُيُوتِكُمْ حَتَّىٰ تَسْتَأْنِسُوا۟ وَتُسَلِّمُوا۟ عَلَىٰٓ أَهْلِهَا ۚ ذَٰلِكُمْ خَيْرٌۭ لَّكُمْ لَعَلَّكُمْ تَذَكَّرُونَ ﴾

So a person must say ‘Peace be upon you may I enter?’ as is stated in one hadīth. That is better for you than entering without permission that perhaps you might remember tadhakkarūna the second tā’ of tatadhakkarūna has been assimilated with the dhāl the superiority of such conduct and so follow it.
