Sayyidina Abu Hurayrah (RA) reported that Allahs Messenger (SAW) said “If anyone relieves a Muslims hardship in this world then Allah will remove from him a hardship of the hereafter. And if anyone conceals a Muslims fault then Allah will conceal (his fault) in the world and the hereafter. And Allah goes on helping the slave as long as the slave helps his brother.
[Muslim 2699, Abu Dawud 4946, Ahmed 7431]
