So, which Dajjalic system was abolished permanently by Mirza Ghulam Ahmed Qadiyani Saahab?
Prophets of Allah only come to sow the seed. It is their followers to accompish the final goal.
If you understand the reality of Dajjal, you will understand how it is being defeated.
Dajjal is the christian civilization. Its religious war was waged during the colonial era and Promised Messiah (as) provided a whole treasure of arguments against christian missionaries who were spreading their creed among the muslims. This will explain "breaking the cross" prophecy.
Right now, no progressive, intelligent human being can associate themselves with the Christian dogma and keep their prestige in the modern world. Why? Because christinaity has been thoroughly defeated. The remnants are fighting for their survival.
The other aspect of dajjal is ignorant clergy among muslims who have lead a vast majority of muslims astray, away from the spirit of Islam. Quran has spoken of their historic jewish counterparts as monkeys and pigs. And hadith also speaks that Promised Messiah (as) will "slay the swine". Many mullahs who opposed Promised Messiah (as) during his lifetime and afterwards persecuted his followers are being slain, humiliated, destroyed by Divine hand. This is another sign of the truthfulness of Promised Messiah (as).
Dajjal is also a materialist. Transforming its followers into atheists and material pursuits. Muslims non-muslims alike. Promised Messiah (as) started a community of followers who believe in a living God who still hears the prayers of Humanity, Who helps His servants. The Ahmadiyya community is a Jamaat, with a Khalifa, fuliflling yet another prophecy of khilafat ala minhaaj e nabuwwat. This Jamaat strives to sarifice life, wealth and honor for the sake of Islam. The concpiracy theorists go on and on about British, CIA, Israeli funding, but the truth is that all works charitable and religious carried out by us are funded by the members of the Jamaat. Each and everyone of us tries to sacrifice as much as we can.. Another reply to Dajjali fitnah..
The list goes on and on..
