The Prophet (peace and blessings be upon him) taught us that:

Believers are like one body; if one member aches, the other members ache for it with fever and sleeplessness. (Bukhari and Muslim)


`The Muslims are to each other like the structure of a building. Each part of it gives support to the others.’ Then the Blessed Prophet intertwined the fingers of one hand together with the fingers of the other. (Bukhari)
