Abu Hurairah (r.a.) narrates that Rasulullah (s.a.w.) said:
If anyone removes one of the anxieties of a distressed person in this world, Allah will remove one of the anxieties of the Hereafter from him. If anyone conceals a fault of a Muslim, Allah will conceal his faults in the Hereafter. Allah keeps helping a man, so long as he keeps helping his brother.
(Musnad Ahmad)
