When to say: “The Decree of Allaah, He does whatever He wills”

Supplication when stricken with a mishap or overtaken by an affair

Qadarullaahi wa maa shaa’a fa ‘ala
It is the Decree of Allaah and He does whatever He wills [1]

[1] The strong believer is better and more beloved to Allaah, than the weak believer and there is goodness in both. Strive for that which will benefit you, seek help from Allaah and do not despair. If a mishap should happen to befall you then do not say ‘ If only I had acted….such and such would have happened’. Rather say:     ‘Allaah has decreed and what He wills, He does’.    … for verify ‘If’ lets in the work of the devil.’ [Sahih Muslim 4/2052]
