Sahih al-Bukhari Book 78, Hadith 56
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.
(the wife of the Prophet) A group of Jews entered upon the Prophet (ﷺ) and said, "As-Samu-Alaikum." (i.e. death be upon you). I understood it and said, "Wa-Alaikum As-Samu wal-la'n. (death and the curse of Allah be Upon you)." Allah's Messenger (ﷺ) said "Be calm, O `Aisha! Allah loves that on, should be kind and lenient in all matters." I said, "O Allah's Messenger (ﷺ)! Haven't you heard what they (the Jews) have said?" Allah's Messenger (ﷺ) said "I have (already) said (to them) "And upon you ! "
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."
