The Prophet (sawa) said, ‘When anyone of you enters his own house, he should greet with peace, for it brings down blessings, and angels come to keep him company.’

the tree

“Abu Abdullah (as): “regarding the tree which the man uproots from his house, inside the Al-Harram’. He said; ‘If the house was built and the tree was in it, then it is not for him that he uproots it; but if it was such that it grew in his house and it is for him, then he can uproot it’.” Al Kafi, Vol. 4, h. 30
