Believers in their mutual kindness, compassion and sympathy

The Prophet, , said: 

“‎The believers in their mutual kindness, compassion and sympathy are just like one body: when one of the limbs aches, the whole body responds to it with wakefulness and fever.” 

[Al-Bukhaari and Muslim] 

قال رسول الله صلى الله عليه و سلم

مثل المؤمنين في توادهم وتعاطفهم وتراحمهم مثل الجسد إذا اشتكى منه شيء تداعى له سائر الجسد بالسهر والحمى

رواه البخاري ومسلم
