if god afflicts you with harm none can remove it except he. and if he wants good for you none can repel his grace. he makes it reach whomever he wills of his servants. he is the forgiver the merciful.
وإن يمسسك الله بضر فلا كاشف له إلا هو وإن يردك بخير فلا راد لفضله يصيب به من يشاء من عباده وهو الغفور الرحيم
