Making Salaam at the Time of Entering the Home

Hazrat Moulana Ashraf Ali Thanwi رحمه الله once mentioned:

Some people enter their homes without greeting the household (e.g. with salaam) and making their presence known to their families. This manner of entering the home is incorrect. It is part of the etiquette of Islam that at the time of entering the home, one enters with making salaam aloud. The benefit of this teaching is that the wife and the inmates of the house will be able to make themselves presentable if they are not in a state in which they wish to be seen. Similarly, it is possible that there could be non mahram women of the locality present in the home, and without informing them of one‟s presence, one‟s sight could fall on them. It is for this reason that Shari‟ah teaches us to make our presence known at the
time of entering the home. (i.e. through salaam). (Malfoozaat of Hakeemul Ummah رحمه الله)
