Barahin-e-Ahmadiyya Part V was completed after a delay of twenty-three years since Parts I to IV were published. This period served to corroborate the Promised Messiah's(as) mission because it proved that the prophecies documented in the earlier parts came true against all odds, and he had God's full support, for God would not have spared a false claimant for such a long time.
When the Promised Messiah(as) began writing the earlier parts of Barahin-e-Ahmadiyya, he was a solitary man of the most meagre means living in the remote village of Qadian. By the time he wrote Part V, the help of Allah the Exalted had blessed him with international renown with every resource at his disposal and a flourishing community numbering into hundreds of thousands.
In short, Barahin-e-Ahmadiyya Part V is the consummation of arguments in support of the divine origin of the Holy Quran and the Prophethood of the Holy Prophet Muhammad(sas). It is also a living testimony of the claims of the Promised Messiah(as) to be the divinely ordained Messiah of the Latter Days.
