Imam Sadiq (a.s) said the following regarding the verse: “Enter not houses other than your own, until ye have asked permission and saluted those in them: that is best for you.” [The Holy Quran: Nur 24:27] “Asking permission implies greeting and stamping the floor with your shoes at the time you want to enter the house.”
وقال (عليه السلام): في قوله: ﴿لا تدخلوا بيوتا غير بيوتكم حتى تستأنسوا وتسلموا على أهلها ذلكم خير لكم﴾ قال: الاستئناس وقع النعل والتسليم.
