Hazrat Mufti Taqi Saheb ( دامت بركاتهم), after penning the following incident, writes:

“These last advices of Hadhrat Binnori ( رحمة الله عليه) should be inscribed on the heart of every person involved in propagating and spreading Deen.” 

A few days before his demise, Moulana Binnori (رحمة الله عليه) attended a meeting of the Islamic Advisory Council in Islamabad. On the second day of the meeting, some people approached Moulana, requesting him to deliver a bayaan (lecture) which would be broadcasted on television. Moulana politely excused himself and did not accede to their request. This then led to the question of whether television, videos, etc should be used for the sake of spreading and propagating Deen, if it is kept free from immodesty, shamelessness and other such elements which negatively affect peoples character. Although not on the agenda of the meeting, the topic was unofficially being discussed. 
The crux of what Moulana Binnori ( رحمة الله عليه ) said on this occasion is as follows:

I would like to mention one important usool (principle) regarding the topic under discussion. Allaah Ta’ala has not made us mukallaf (duty-bound) to use any and every means possible, in order to bring people onto Deen.Yes, we have most definitely been made mukallaf (duty-bound) to use the various permissible means and methods of propagating at our disposal. Together with commanding us to propagate and spread Deen, Islam has shown us the method and aadaab (etiquettes) of propagating Deen as well.  

We are mukallaf (duty-bound) to propagate Deen, but within the confines of those methods and aadaab.If we, by adopting the permissible methods and means of propagating Deen, achieve our goals and objectives,then well and good. But, supposingly, if we adopt the permissible means and methods, and by so doing, we do not achieve our goals,then we have not been made mukallaf (responsible / duty-bound) to adopt those methods and means declared impermissible by Shari’ah, for the sake of propagating the message of Deen and winning people over to our side. 

If by adopting those methods and means which Shari’ah has permitted, together with the aadaab of propagation, only one person is brought onto Deen,then our propagation efforts have been successful. On the other hand, if by adopting those methods and means which are declared impermissible by Shari’ah, even a hundred people are affected and won over, then this “success” or “achievement” holds no value in the sight of Allah Ta’ala, because that propagation which entails trampling the laws of Deen, can never be the propagation of Deen, but rather it is a propagation of something else. 

Videos and films are itself against the laws of Islam, therefore we have not been made mukallaf (commanded) of using it for the propagation of Deen.
We will extend our heart and soul for those who are prepared to listen to our Da’wah through the correct and permissible means, but as for those who are only prepared to listen to our Da’wah if it is done via those means and methods which are not permissible, like videos and films,then we are ma’zoor (excused) from conveying the message to such persons in such a manner. 
If we do not adopt this stance which has been explained, then today, for the sake of the people, we will be using films to propagate Deen, tomorrow women without pardah/hijaab will be used for spreading Deen, and we will try to bring people onto Deen through gatherings of music and dancing… And In this way, in the name of propagation of Deen, we will be trampling upon ad destroying the laws of Shari’ah, one by one.
