Sahih Muslim Book 45, Hadith 83
A believer is like a brick for another believer, the one supporting the other.
Leave it. for it is something disgusting. Ibn Mansur said that in the narration transmitted on the authority of Amr (these words are also found):" I heard Jabir."
The similitude of believers in regard to mutual love, affection, fellow-feeling is that of one body; when any limb of it aches, the whole body aches, because of sleeplessness and fever.
