When Entering An Empty or Vacant House, Say…
 

عن عبد الله بن عمر قال: "إذا دخل البيت غير المسكون، فليقل: السلام علينا، وعلى عباد الله الصالحين"

Abdullah ibn Umar (may Allah be pleased with him) said: When someone enters a vacant home, he should say, “Peace be upon us and on the righteous salves of Allah.”

Collected by Bukhari in Adabul Mufrad 1055] Graded as being Hasan by Ibn Hajr and Al-Albani (may Allah have mercy on them both)

Al-Albani (may Allah rest him in Jannah) said, “This narration establishes an Islamic regulation for entering a vacant house. This practice coincides with the order of spreading salaams found in some authentic hadeeth. Furthermore this Athar agrees with the verse, “When you enter your houses greet one another with: As-Salamu 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 salves of Allah, when entering an empty house as well.

The Hadeeth for saying,” (In the name of Allah)”, when entering the home is authentic on the authority of Jabir (may Allah be pleased with him). It is collected in Muslim. The Prophet (peace and blessings be upon him) said,”

إِذَا دَخَلَ الرَّجُلُ بَيْتَهُ فَذَكَرَ اللَّهَ عِنْدَ دُخُولِهِ وَعِنْدَ طَعَامِهِ قَالَ الشَّيْطَانُ لاَ مَبِيتَ لَكُمْ وَلاَ عَشَاءَ

If a man enters his home and says” in the name of Allah” and before he eats, Shaytan says to his Jinn ,” You can’t stay there tonight and you can’t eat there as well.” [ Muslim 5381]
