Allah said, "Believers should not venture into other people's houses until you ask their permission and say hello to their owners. This is better for you, so that you may take heed. If you find that the owner is not here, don't go in until you get permission. If someone says to you, "Please go home!" "You should look back at once, so it is more pure for you. God knows your's behavior. " (Koran, Chapter 24, Verses 27-28)
According to the legend of Sai Lihai, a man came to the prophet's bedroom, and the sage said to him with an iron comb, "Suppose I knew you were peeking, I would stab you in the eye with an iron comb. God stipulated that you should ask for permission when asking for permission." Another biography said: "The prophet held an arrow and seemed to stab it.
According to Abu Hulle's biography, the prophet said, "Anyone who snoops into a room without permission can gouge out his eyes."
He added, "Anyone who screws people without permission may be stoned to death and his eyes gouged out."
According to Abdullah's biography, "once, when a prophet came to someone's door, he didn't stand facing the door, but just stood on the right or left, waiting for his master to open the door."

According to WIM Lemaitre, after I was ordered to use the veil, WIM and I were in Mu Sheng, Ibn? Mamstrom came, and Musheng said, "You two hide!" We said, "Prophet! He is blind, can't see us, and can't recognize us. " Musheng said, "Are you two blind, too? Didn't you see him? "
To sum up; Islam stipulates the etiquette of visiting;
1, it is forbidden to spy on other people's homes, whether from the outside, from the hole, from the window or from other places.
The advantage of asking for permission is to stay away from what God forbids.
3, should choose the appropriate time to visit.
4. Knock gently on the door; According to irons, "there are often people who gently knock on the saint's door." Buhari hadith
People who want to visit should stand on the left or right side of the door and ask for permission. Don't peek at home, because the host doesn't want anyone to see his home, but asks for permission to avoid embarrassment.
You should say hello before asking for permission. According to lapierre, when the sage was at home, an Amil family visited him. He said outside the door, "May I come in?"
