Be patient and listen attentively till the end of the lecture. I agree with what the person who posted the video wrote regarding this.
"Ustadh Nouman Ali Khan takes a very unique approach to an important aspect of our Deen, well I don't want to give away what this lecture is all about because the audience will get to know that at the very end of the lecture.
I thought that he will be speaking about the importance of the relationship between the spouses and the children because of the dua in surah Al-Furqan verse 74 being mentioned. Well he kind of touched on that subject as well but that is not what the lecture is all about. Overall a very classy approach to the issue at hand."
