Sahih al-Bukhari Book 78, Hadith 43
The Prophet (ﷺ) said, "If any Muslim plants any plant and a human being or an animal eats of it, he will
be rewarded as if he had given that much in charity."
Allah's Messenger (ﷺ) said, "You see the believers as regards their being merciful among themselves and showing love among themselves and being kind, resembling one body, so that, if any part of the body is not well then the whole body shares the sleeplessness (insomnia) and fever with it."
The Prophet (ﷺ) said, "He who is not merciful to others, will not be treated mercifully.
