and if allah afflicts you with some suffering there is none who can remove it except him and if he wills good for you there is none who can repel his munificence he bestows it upon whomever he wills from among his bondmen he is the oft forgiving the most 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
