Translation of the verse 3 from Surah Al-Fath : Number of verses 29 - - page 511 - Part 26.
And that Allah may help you with strong help.
And [that] Allah may aid you with a mighty victory.
(48:3) and that Allah may bestow upon you a mighty help. *5
*5) Another translation can be: "Bestow on you an unprecedented victory," for the word aziz in the original may mean mighty as well as unprecedented and unparalleled. According to the first meaning, the sentence means: "By means of this treaty AIIah has helped you in a way as to make your enemies helpless"; and according to the second, it means: "Seldom has this novel method ever been adopted to help somebody, that a thing which apparently is a mere peace treaty, and that too a treaty concluded from a weak position, would turn into a decisive victory."
