question #3 Sahih al-Bukhari 6026, 6027, Book 78, Hadith 57 : How does helping others and making recommendations relate to receiving rewards in Islam?

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.”
