Keep your house clean and free from impurities; Respect God's messengers/angels; Avoid having anything impure such as statues or people who are junub in your home; Do not bring dogs into your home.

This hadith speaks to the importance of keeping one's house clean and free from impurities. It was narrated by 'Abdullah bin Nujayy that Ali said he used to enter upon the Messenger of Allah twice, by night and by day. If he entered upon him while he was praying, he would clear his throat. One night, when Ali entered his house, the Messenger of Allah told him that an angel had been waiting for him all night but could not enter because there was a dog in his house or someone who was junub or a statue. This shows us how important it is to keep our houses clean so that angels can come in them without any hindrance. We should also be mindful not to have anything impure in our homes such as statues or people who are junub so that we can receive blessings from God's angels without any obstruction.
