Hadees Related to Intention (Niyat)

Anas ibne-Malik Radiyallahu 'anhu narrates that Rasulullah Sallallahu 'alaihi wasallam said: You have indeed left behind in Madina people who will have an equal share in reward in no matter whatsoever path you travel or whatever you spend and whatever
valley you cross. The Sahabah asked: O Rasulallah! How can they be with us when they are in Madina? He said: They intended to go out with you but were detained by a valid reason. (Abu Dawud)
