Sahih al-Bukhari Book 78, Hadith 57
The Prophet (ﷺ) said, "A believer to another believer is like a building whose different parts enforce each
other." The Prophet (ﷺ) then clasped his hands with the fingers interlaced. (At that time) the Prophet (ﷺ) was
sitting and a man came and begged or asked for something. The Prophet (ﷺ) faced us and said, "Help and
recommend him and you will receive the reward for it, and Allah will bring about what He will
through His Prophet's tongue."
A bedouin urinated in the mosque and the people ran to (beat) him. Allah's Messenger (ﷺ) said, "Do not interrupt his urination (i.e. let him finish)." Then the Prophet (ﷺ) asked for a tumbler of water and poured the water over the place of urine.
Whenever a beggar or a person in need came to the Prophet, the Prophet would say "Help and recommend him and you will receive the reward for it, and Allah will bring about what he will through His Prophet's tongue
