ENTERING AN EMPTY or VACANT HOME.
Abdullah ibn Umar (may ALLAH be pleased with him) said: When someone enters a vacant home, he should say, “BismilLah, As-Salaamu ‘Alaynaa wa ‘Alaa ‘Ibaad-Allah-is-Saliheen” (“Peace be upon us and on the righteous slaves of ALLAH.”). Collected by Bukhari in Adabul Mufrad 1055].
Sheikh Al-Albani (may ALLAH rest him in Jannah) said, “This narration establishes an Islamic regulation for entering a vacant house or your house when no one is inside. This practice coincides with the order of spreading salaams found in some authentic hadeeth. Furthermore, this agrees with the verse, “When you enter your houses greet one another with As-Salaamu Alaikum…[ An-Nur 61].
Therefore based on this verse and narration from Ibn Umar (may ALLAH be pleased with him) Ibn Hajr held it was recommended to say, “Peace be upon us and on the righteous slaves of ALLAH, when entering an empty house as well or even in our cars etc as we are always walking with 2 Angels with us isn’t it?. AlhamdulilLah for HIS guidance.
May ALLAH (Al-Haadi, The Guide) keep guiding us all. Aameen.
