It is We Who created them, and We have made their joints strong;(5859) but, when We will, We can substitute the like of them(5860) by a complete change.
5859 Allah has not only created men, but "made their joints strong", i.e., given them the power and strength to withstand the temptations of Evil and stand firmly in the Padi of Right. 5860 If, in spite of Allah's loving care, any particular men or group of men, misuse their powers or wilfully disobey Allah's Law, Allah will set them aside, and substitute others in their place, with like powers. Allah's gifts are free, but let no one think that he can monopolise them or misuse them without being called to answer for the trust. And the man of Allah must not be discouraged by the whole world being at some moment completely against him. Allah can in a moment make a complete change. Either the same men that fought against him will be his zealous adherents, or another generation will spring up, which will carry the flag of Righteousness to victory. Allah's Will and Plan work in their own good time.
