In the name of Allah, Most Gracious, Most Merciful.
Narrated Abu-Sa’eed Al-Khudri and Abu-Huraira (may Allah be pleased with them): ‘The Prophet (May Allah exalt his mention and protect him from imperfection) said: “No fatigue, no disease, no sorrow, no sadness, no hurt, no distress befalls a Muslim, even if it were the prick he recieves from a thorn, but that Allah expiates some of his sins for it.” (Bukhari)
