Angels

السلام عليكم

بِسْمِ اللهِ الرَّحْمنِ الرَّحِيمِ

"The angels do not enter a house in which there is a dog or a portrait"

[Al-Bukhari and Muslim]

Angels here refers to angels of mercy whose visit is a blessing for homes;the angels who supervise us and record our deeds are with us at all times.
