Sahih al-Bukhari Book 78, Hadith 42
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."
Allah's Messenger (ﷺ) stood up for the prayer and we too stood up along with him. Then a bedouin shouted while offering prayer. "O Allah! Bestow Your Mercy on me and Muhammad only and do not bestow it on anybody else along with us." When the Prophet (ﷺ) had finished his prayer with Taslim, he said to the Bedouin, "You have limited (narrowed) a very vast (thing)," meaning Allah's Mercy.
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."
