It is narrated from Sayyiduna Husayn bin Ali (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: If any Muslim man or woman has suffered a hardship, even if a long time has passed since it occurred, and then he or she recites "Inna lillahi wa inna ilayhi raji'un" anew, Allah Almighty restores the previous state for him and grants him the same reward as was given on the day of the calamity.
