When I initially began my Da’wah efforts to the Ahmadis, I was under the impression that evidence and reasoned logic were sufficient to convince anyone of the truth. But, throughout my discussions with many ex-Ahmadis who embraced Islam, I realized that while the evidence was certainly a part of their conversion experience, the biggest factor was visiting a thriving Muslim community and seeing the reality of our general community, leadership and scholars.
Does Reason Work?
In the past, I have shown many arguments on the failures of Ahmadiyya and the superiority of Islam. Open-minded Ahmadis have told me the arguments have made them question. But, not-so-open-minded Ahmadis will posit a response no matter how ludicrous it is. For example, with the help of Brother Shahid, we demonstrated clear-cut grammatical errors in Mirza Ghulam’s alleged English revelations. When unable to find a technicality to justify his clearly grammatically incorrect English, defenders of Ahmadiyya resorted to:
Is perfect grammar a REQUIREMENT of truthfulness?
And no matter how hard you try, you can never break this argument! 
-SultanulQalam Canada
This is not a response, this is an acknowledgement of error. (And it goes against this verse) Had we observed faulty English in the likes of Baha’iullah, no Ahmadi defender would have objected to rejecting him. But, because the claimant happens to be Mirza Ghulam, the close-minded will employ Sophistry and give any possible response to vindicate a clearly erroneous position.
So does reason work? Yes, many are convinced by the reason and logic that Islam offers over Ahmadiyya. This has proven to be fruitful for many. But, I also defer to what Imam al-Ghazali wrote in his Deliverance from Error:
Anyone who believes that the unveiling of truth is the fruit of well-ordered arguments belittles the immensity of divine mercy.
The Effective Approach
Ahmadis are told that the Muslims are astray, without any leadership, utterly divided into countless sects, led by “jahil mullahs” and essentially inviable.
But, when they actually visit a masjid, a different picture sinks in. As Farhan Qureshi says in the video about his conversation, he expected to see “bearded mullah terrorists”, but instead was amazed at the thriving community he witnessed. Another convert to Islam from Ahmadiyya told me when he visited the Muslims in Ramadan, the connection to Allah that he experienced was far superior to anything he saw in Ahmadiyya.
There are countless other stories on the same pattern. Ahmadis convert to Islam when they see our communities. They question, “if the Muslims are not as bad as we are taught, in fact quite the opposite, what then was the purpose of the Ahmadiyya community to begin with”?
Do reason and logic have a role? Most certainly yes! But, from my perspective it does not seem to be the dominant reason. Islam is not a religion that is conveyed from books and well-formed arguments. Even the Qur’an required the Prophet Muhammad صلى الله عليه و سلم to explain it and guide with it. Islam is conveyed from Heart to Heart.
Thus, a better approach might be to show the Ahmadis our community. To invite them to our masjids. To send them our literature that has nothing to do with Ahmadiyya (which is pretty much all of it anyways). To genuinely befriend them, offer them help when needed, treated well, and be their personal invitation into Muslim community. And, if the only access we have to them is through an internet medium, have them listen to our Sheyookh over YouTube.
Based on my experience, this seems to be a very effective approach. As in all things, there are two main difficulties ahead:
A) Are we able to humble ourselves and be patient enough to slowly wean Ahmadis towards Islam? Or are our intentions so corrupt that we only seek to argue, insult and ridicule, thus further driving them away from the Truth? This means no more negative comments directed at them. Even those comments that expose their faults must be done so with kindness and humility.
B) Violence and persecution against them. Those who attacked their centers in Pakistan did nothing but commit one of the worst sins: murder of innocent life. And, they helped instill a siege mentality whereby ordinary Ahmadis are emotionally attached to the religion even if they recognize it as a misguidance.
In our dealings with Ahmadis, let us not follow the Sunnah of Mirza Ghulam, who resorted to cursing and insults. Let us follow the Sunnah of the Prophet Muhammad صلى الله عليه و سلم who guided the most wretched kufaar to the greatest religion.
May Allah continue to guide the Ahmadis to Islam.
