Muslim (918) narrated that Umm Salamah (may Allaah be pleased with her) said: I heard the Messenger of Allaah (peace and blessings of Allaah be upon him) say: “There is no Muslim who is stricken with a calamity and says what Allaah has enjoined – ‘Verily to Allaah we belong and unto Him is our return. O Allaah, reward me for my affliction and compensate me with something better’ – but Allaah will compensate him with something better.”
