- " إذا اشتكى المؤمن أخلصه الله كما يخلص الكير خبث الحديد ".
It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Noble Prophet (peace and blessings of Allah be upon him) said: "When a believer falls ill, Allah, the Exalted, purifies him (of sins) just as a furnace removes impurities from iron."
