The Prophet of Allah, sallallaahu ‘alayhi wa sallam, informed that a Muslim will be rewarded for every calamity, even if it is small and insignificant

“For every hardship, disease, worry, distress, harm, and grief that a Muslim faces, and even for every thorn that pricks them, Allah will expiate some of their sins through it.”

“I entered where the Messenger of Allah, sallallaahu ‘alayhi wa sallam, was, and found him suffering pains of a fever, and I said: ‘O Messenger of Allah, you are suffering severe pains of your fever,’ and he, sallallaahu ‘alayhi wa sallam, said: ‘Yes, I am suffering as much as two men among you would suffer.’ I said to him, ‘For that reason, will you have two rewards?’ He, sallallaahu ‘alayhi wa sallam, said: ‘Yes, it will be as you said; there is not a Muslim that is afflicted with the harm of a thorn, or anything above that, except that because of it, Allah will expiate their sins, and his sins will fall like leaves fall off a tree.’”
