Narrated by ‘Aisha (the wife of the Prophet) (Radiyallaahu `anha), The Prophet (Sallallaahu `alayhi wa sallam) said,
“No calamity befalls a Muslim but that Allah expiates some of his sins because of it, even though it were the prick he receives from a thorn.”

Narrated Abu Huraira (Radiyallaahu `anhu), Allah’s Apostle (Sallallaahu `alayhi wa sallam) said,
“If Allah wants to do good to somebody, He afflicts him with trials.”
