Remain patient and faithful to God even when facing hardships.

This hadith is about the reward that comes with suffering. It was narrated by Abdullah who visited the Prophet Muhammad during his ailments and saw him suffering from a high fever. When Abdullah asked if he would receive double reward for it, the Prophet replied yes, because no Muslim is afflicted with any harm but that Allah will remove their sins as leaves of a tree fall down. This hadith teaches us that no matter what kind of difficulty or hardship we face in life, Allah will always be there to help us and forgive our sins if we remain patient and faithful to Him. We should never lose hope in times of difficulty because Allah has promised us rewards for our patience and faithfulness.
