Mukhtasar Bukhari

It is narrated from Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "A believer to another believer is like a building, each part strengthening the other." And he interlaced his fingers to illustrate how they support each other. (Once it happened that) the Prophet (peace and blessings be upon him) was sitting when a person, either a beggar or someone in need, came. The Messenger of Allah (peace and blessings be upon him) turned towards us and said: "Intercede on behalf of this person, you will be rewarded, and Allah causes what He wills to be spoken by the tongue of His Prophet (peace and blessings be upon him)."
