ENTERING OR LEAVING A HOUSE

How to Enter?

When entering or leaving a house, do not push the door violently, or leave it to close by itself wildly.

Such actions stand in contrast to the politeness of Islam which you are honoured to belong to. Close the door gently with your hand. You may have heard a hadith reported by Imam Muslim 
 whereby Sayyidatuna ‘Aishah (r) quotes the holy prophet (pbuh) as saying:

“Gentleness adorns every act and its absence tarnishes it.” [Sahih Muslim]

Greeting

When entering or leaving your house, acknowledge those inside. Use the greeting that is unique to Muslims and which is the label of Islam:

Assalamu’alaikum wa rahmatullahi wa barakatuh

“Peace, mercy and blessings of Allah be upon you.”

Do not forego this Islamic greeting by replacing it with something else such as “Good Morning” or “Hello” etc. This will lead to the “Salam” eventually being totally abandoned. This greeting is the salient feature of Islam. It is the label of the Muslims which the holy prophet (pbuh) prescribed by his action and statement and it is that which he taught to his attendant, Sayyiduna Anas Ibn Malik (r) when he said to him:

“O my son, greet your family when you enter (your home) for that is a blessing for you and your family.” [Sunan Tirmidhi]

Imam Qatadah (r), a prominent Tabi’i said, 
“Say salaam to your family when you enter your house, for they are the most worthy of your Salaam.”

Imam Tirmidhi recorded from Sayyiduna Abu Hurairah (r) that Rasulullah (pbuh) said:

“When any of you joins a gathering, he should say Salaam and when he intends to leave, then too, he should say Salaam. The first (the greeting of arrival) is no less important than the second (the greeting when parting).”
