Re: Teachings of Mujaddiths who follow Haneefi Madhab
I've had a similar experience. I'm friends with a number of TJs and I've discussed a few things with one of them. He presented me with the same explanation that it's okay to use weak ahadith for the sake of dawah. In addition, he said there might be some truth to it, so they cannot rule it out.
Just like you I had a hard time believing. I left it at that.
