- " ما من عبد يصرع صرعة من مرض، إلا بعثه الله منها طاهرا ".
It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no (believing) servant who is laid low by illnesses, but when Allah, the Exalted, raises him up (by granting him recovery), he becomes purified."
